    Demodulated 3dB Bandwidth

    Input the above signal and sweep the carrier around 455 kHz, and find

    Out the maximum audio output frequency. Then sweep the carrier frequency again and find two frequencies, which are observed

    –3dB attenuation points from the maximum point.

    Higher frequency point is called (f1) and lower called (f2). (F1-455KHz) is defined as upper 3dB bandwidth and (455KHz-f2) defined as lower

    3dB bandwidth.

     

     

     

     

     

     

     

     

     

     

     

     

    Demodulate Output

    Demodulated output shall be measured when carrier frequency is adjusted to 455KHz.

     

     

     

    Demodulated

    Distortion Factor

    Carrier frequency is adjusted to

    455KHz.And distortion shall be measured with 1 kHz modulation frequency.
