    Input signal condition

     Input level 80dBμ
    Frequency Deviation ±4.0 kHz
    Modulation Frequency 1.0 kHz
    Demodulated 3dB Bandwidth

    Input the above signal and sweep the carrier around 450 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). (F1-450KHz) is defined as upper 3dB bandwidth and (450KHz-f2) defined as lower 3dB bandwidth.

     
    Demodulate Output Demodulated output shall be measured when carrier frequency is adjusted to 450KHz.  

    Demodulated Distortion Factor

     

    Carrier frequency is adjusted to 450KHz.And distortion shall be measured with 1 kHz modulation frequency.
