The manual notch filter is a notch filter with a frequency that can be shifted with the notch knob. The
auto notch filter is a notch filter that automatically tracks a beat frequency with an adaptive filter
technique. Both notch filters have the attenuation of more than 60 dB at the center frequency. Figure
4-7 describes how a weak signal emerges by the operation of AGC when the manual notch filter
eliminates an interfering signal in the power spectrum.
