A
The local oscillator frequency is beating against the incoming signal to produce an Intermediate Frequency (IF).
B
The output signal of the Phase Locked Loop (PLL) circuit in the frequency synthesizer has become unlocked.
C
The output signal of an AF amplifier stage is greater than the input signal.
