 AM signal demodulation option
 -------------------------------------------------

 1. You can apply this analysis to any AM signal to
    demodulate it and extract its content 
 2. When you choose this option dialog appears with
    two options:
    - Sample rate of new signal: You can determine SR
      for new signal. Higher value increases evaluation
      time
    - Demod precision: Precision for FFT while evaluating
      demod signal. Higher value increases evaluation
      time
 3.  After pressing OK, demodulated signal appears

 4.  You can apply same option for Real Time demodulation:
     Start Sound Card acquisition window with 44100 sample
     rate and 16384 (alternates 8192,32768) window length.
     When window appears, choose AM demodulation option. 
     Minimize or hide windows you don't need and start
     acquisition. (you must have full-duplex sound card)

 Algorithm: It's very simple. You can see it if you activate 
 Control Window (Ctrl+W). Everything is done in one Time FFT,
 end extracted as a ruler with (Extract X-Ruler option). 

 New demodulated signal has AutoPlay option set, so on every
 change it will be played on sound card. (necessary for real-time
 demod)
