RTL SDR IQ AM Demodulation

QUESTION

RTL SDR IQ AM Demodulation

Asked 2020-Apr-10 at 23:23

The project i am working now currently is tuning to PMR frequencies and saving audio to a WAV file, however when i receive IQ samples from SDR device, and demodulate to AM - i hear noise only.

Edit, here is the RAW IQ written to WAV file: https://voca.ro/iSRELps4JBg

For demodulation i used this approach:

However the sound seems to be noise...

Your code is for an FM demodulator (frequency as the derivative of phase, or phase delta in the discrete case). For AM demodulation, you only need to get the magnitude (abs()) of the IQ components, and low pass filter.
