I need a complete phase-shift keying (PSK) circuit designed, simulated, and documented. The task starts with drawing a clean, logically laid-out schematic, then moves on to running a thorough simulation that verifies modulation and demodulation performance under realistic conditions. I have a template circuit but it needs formatting to the correct pins. You are free to pick the tool you know best—LTspice, Multisim, MATLAB/Simulink, or any other platform that can deliver trustworthy waveforms and numeric data—as long as the final results are reproducible on my end. What I expect in the hand-over: • A clearly annotated circuit diagram showing every component value and reference designator. • Simulation files plus screenshots or plots of key signals (carrier, modulated output). • A concise report that walks through the design rationale, parameters used, and an interpretation of the results, finishing with a short conclusion on performance and possible improvements. Accuracy is essential, so please double-check component models and any assumptions you make.

Hi, I’m an electronics and signal-processing engineer at Live Experts LLC. I can take your PSK template circuit, clean up the schematic, correct the pin formatting, assign proper component values/reference designators, and then run a full reproducible simulation to verify both modulation and demodulation behavior. My approach would be practical rather than just academic: first I’ll review your template and assumptions, then rebuild the circuit in the most suitable tool such as LTspice, Multisim, or MATLAB/Simulink, depending on what you prefer to open and reproduce later. I’ll capture the key waveforms including carrier, modulated signal, demodulated output, and any relevant timing/noise behavior so the results are easy to verify. You will receive the editable simulation files, a clean annotated schematic, waveform screenshots/plots, and a short technical report explaining the design logic, selected parameters, assumptions, results, and possible improvements. Accuracy and reproducibility will be the focus, so I’ll double-check component models, connections, and simulation settings before delivery. I can start as soon as you share the template circuit and any required PSK type such as BPSK/QPSK.
