I have well-working Python code that performs FFT of an audio signal from a microphone. I need help adding some additional code that will compare different microphone values to a specific set value. Based on the match between the microphone values and the set value the code needs to export corresponding PWM signal to two output pins.

Hello I have a Channel Impulse Response matrix which is 4D and have to convert that to Channel frequency response matrix, i know it can be done by FFT but i need to know the relation between the two. You only need to explain few things, like how can i extract signal and others. There is no coding involved. Thanks

Hello I Hello I have a CIR matrix of shape (t,Tx,Rx,p) where: The file has a data set of MIMO CIR of size (1400, 4, 4, 8) l: time snapshots (use one of them as the 3D CIR matrix, transform it to CFR and compress/reduce it) p: impulse response in time domain. rx - Number of receive antenna tx - number of transmit Antennas I need to know how can I transform CIR to CFR ? I know I have to do fft but which dimension of CIR I can squeeze. Is there signals in CIR matrix which i can extract. The thing is I have to do SVD and OMP on CFR matrix, for this i need input signals for equation like "y=Hx + w", can i extract those from the CIR or CFR matrix so obtained.

Create FFT spectrum of left channel audio out and subtract the FFT frequency spectrum of Microphone IN - the result is is what is called transferfunction - then turn this frequency spectrum again in audio time domain and output it on right channel - this is a therapeutic app where the patient gets to hear a sound on the left ear - tries to reproduce this sound as best as he can by humming into the microphone - and then gets to hear the transferfunction on his right ear which is then a combination of all frequencies that were missing in his humming relative to the played sound in his left ear

FFT integration according to the pdf documentation sent previously. For testing will be used a .wave file. Input variables will be in a separate config file.

Frequency domain transforms are extensively used in signals and systems applications. This project involves a comparison of the direct implementation and FFT implementation of discrete Fourier transform (DFT). As indicated by the DFT equation below, for the DFT computation, the samples in a frame of length N are needed and not just a single sample. In other words, DFT/FFT computation occurs in a frame-based manner. In frame processing, N samples are captured first and then all of the N samples are needed to compute the DFT coefficients. The DFT equation describing the frequency transformation is given by: ?[?] = ∑ ?[?] ∗ ?? ?? ?−1 ?=0 , ? = 0,1, … , ? − 1 where WN=e-j2π/N. To compute a DFT term, N complex multiplications and N-1 complex additi...

We have a metering hardware which takes simultaneous samples of the three voltage waveforms and three current waveforms in a three phase electrical system. These signed samples are filled in an array of 128 members. Thus , there are six arrays , each filled with 128 signed values. We are presently running FFT code on each of these arrays and arriving at the strength of individual odd harmonics ( normalised against the fundamental ) and represented as percentages. e.g. In case of R phase current , we say that 3rd harmonic is 11% , 5th harmonic is 7% , 7th is 4%.....and so on upto 31st. We also arrive at the THD figure for the six waveforms. Now , we need to perform an additional task .i.e. to determine the source(direction) of these individual harmonics; because the third harmonic b...

I have a project built on flutter. In that i want to read the frequency of the recorded sound. (There can be some noise in the recording audio, so it should be excluded in the output). I understand that FFT has to be implemented, but i am not sure on how it can be implemented. What i am looking for: Should read the audio file and print the frequency and if possible frequency graph too.

Hi, I would need a comparison of four different models for a time series forecasting project. The four algorithms that need to be implemented are - Fast Fourier Transform Forecasting model (FFT) - Theta model - Multi layer perceptron model (MLP) - Convolutional Neural Network model (CNN) I want the prediction on an hourly resolution. The single variable which needs to be forecasted is the PM25 value from the attached dataset. PM 2.5 refers to a category of particulate pollutant. The implementation should be in python using a jupyter notebook. Thanks,

I have a program called fosphor which essentially displays the FFT histogram from a complex IQ radio signal. You can find the software here The histogram in the UI is limited to 1024 samples though, so I want to create a version that allows me to save the histogram continously into a binary file that can be read later, to retrieve the data in a random access manner. I assume to solve my issue, less than 100 lines of code have to be added/changed only. I have already inspected the code and understand most of it, though I was unable to deal with the background/transparceny/colormap or such correctly when exporting the data myself. I basically got the data but the colormap does not match, so the image appears very off. To finish this project,

We need a network tester for our clients to verify that they have adequate network connectivity for our application. We've found 2 JavaScript open-source projects that can produce the functionality we need. A third JS open-source project displays an FFT spectrogram of the microphone input. We’d like to combine these with vue-chartjs for the line chart and progress bar. After the tests have been run, the results are collected and passed to a testSummary component. This component will have hardcoded warning and error thresholds for the test results. These results are show as the value and a “traffic light”. Red if under error threshold, yellow if under warning threshold and green otherwise. The attached diagram shows the calling function and the 6 components. ...

...mask is shown as applied in ) - : an RGB image - : the expected result Please note that the module is not expected to load images from disk but to receive images as or variables as described above. Compatibility --------------------- The module has to be compatible with Python 3.8+, should depend only on public domain software (licensed under BSD, Apache 2.0 or similar) and should work on Linux (Ubuntu Server). The module must not depend on Gimp, QT5, GTK or any other similar software/libraries. You can share a dependences list so we can check all elements are compliant with our requirements. Result ---------- As said above, the expected result is a fully compliant PSD file. If required, detailed PSD specifications can be found here: https://www

Currently we are experimenting with a proof-of concept web app written in Node.js that acquires the samples via bluetooth web api, calculates signal spectrum with FFT and displays both the raw signal and spectrum for one channel. Google graphs are used for drawing the signals. It seems that the web application as we have currently created is not optimized well as it barely manages to refresh the graphs at 10 or so fps for only one channel on an average modern laptop.

I'm asking for a client-server hangman game with the specifications listed below, written in C/C++ with the use of BSD Sockets. You can start from scratch, but I already have a program that just needs some slight improvements. You would just have to change the scoring system/some basic rules according to the specification, fix the category to make it displayed next to the word instead of being a part of it, make the results of other players visible during the play, and maybe add a basic visual representation of a hangman. If possible, multiple rooms should be added as well, but first, focus on the other changes regarding just one room. This might take a bit more time, and I'd like to have it rather soon. You can find the current program attached in a zip file, I think the...

The specification is attached below. The GUI doesn't have to look great. Keep it simple. In general, the program doesn't have to be perfect (worst case some requirements can be omitted) but should be done in a week, preferably a few days. When done, please also attach instructions on how to compile and use it, with the required installations. Preferably, it shouldn't be too complicated and consist of too many files, as far as it's possible.
