*Sensitivity Conditions
AM - An input signal AM modulated 50% by a 1-kHz tone produces a minimum video output
S+N/N ratio of 10 dB.
FM - An input signal FM modulated at a 1-kHz rate with a peak deviation equal to 30% of the
selected IFBW produces a minimum video output S+N/N ratio of 17 dB. (Note: A 400 Hz
modulation rate is required for IFBWs of 10 kHz or less.)
CW - A continuous RF input signal produces a minimum audio output S+N/N ratio of 16 dB.
