EXAMPLE
An R F signal is applied to the Measuring Receiver. The modulation rate is
1
kHz and the peak
modulation is to be measured in a
IS
kHz post-detection bandwidth. To measure the peak AM
depth and correct for the effects of residual noise on the modulation:
For the purposes of subsequent calculations, assume the displayed AM is 3O.8O0/o.
