4.
Input frequency = 468 kHz; m = 30% modulated with f
mod
= 1 kHz; unless otherwise specified.
Front-end connected to IF plus detector part. Input frequency = 1 MHz; m = 80% modulated with
f
mod
= 1 kHz.
Input frequency = 100 MHz; output frequency = 10.7 MHz.
Input frequency = 10.7 MHz; frequency deviation,
f = 22.5 kHz and f
mod
= 1 kHz; unless
otherwise specified.
Reference: AF output voltage = 0 dB at V
