title: Carrier signal extraction using Amplitude Demodulation using Python
body: <p>I get an IF signal from microwave circuit which looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/OBNi5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OBNi5.png" alt="IF Signal"></a></p>
  
  <p>As we can see there is a distinct unwanted Amplitude Modulation which is believed to be due to coupling between antennae. This signal will also have a FM modulation.</p>
  
  <p>I want to remove this AM modulation so that only FM modulation remains. I want the carrier signal NOT the AM modulation.
  Something like how a Automated Gain Control (AGC) would work.</p>
