component. Two signals in the in-band are
each mixed with signals which will allow ADC
to produce -7dB output signals. The harmonic
and non-harmonic components of the ADC
output signals between 1kHz to 20MHz are
extracted and added. The AGC control
voltage is controlled so that ADC output is full
scale when the input signal is -80dBm.

related to jammer based on 2 jammer signals.
One in-band signal(@50kHz,0.5*F/S)
and two jammers(@900kHz, 22dB*F/S and
@1.7MHz, 21dB*F/S)are simultaneously
input. AGC control voltage is controlled so
that ADC output is F/S when the input signal
is -80dBm.
