Need help designing a active bandpass filter for audio with adjustable center frequency
Betalt ved levering
I am looking for a skilled engineer to design an active audio bandpass filter with an adjustable center frequency for my audio processing application. I am just a hobbyist so i need help from an expert :)
The ideal candidate should have experience in audio signal processing and filter design. The project requirements are as follows:
- Center frequency: 30 Hz
- Bandwidth range: Around 10Hz
- Application: Audio processing
The deliverables should include a circuit diagram and a bill of materials for the filter design. The circuit should be able to adjust the center frequency.
The filter should use max two opamps. The center frequency adjustment should be made with a potentiometer. using the potentiometer. How far can i go with the center frequency? 1000Hz? 20.000Hz?
I have used a filter design tool which gave me the following schematics. Your job would be to tell me how to make it adjustable.
