SQUELCH AMPLIFIER
The circuit of Figure 17 is a simple squelch amplifier that uses a
FET switch to cut off the output when the input signal falls
below a preset limit.
The input signal is sampled by a peak detector with a time
constant set by C1 and R6. When the output of the peak detector
(Vp), falls below the threshold voltage, (VTH), set by R8, the
comparator formed by op amp C switches from V– to V+. This
drives the gate of the N-channel FET high, turning it ON, re-
ducing the gain of the inverting amplifier formed by op amp A
to zero.

FIVE-BAND LOW-NOISE STEREO GRAPHIC EQUALIZER
The graphic equalizer circuit shown in Figure 18 provides 15 dB
of boost or cut over a 5-band range. Signal-to-noise ratio over a
20 kHz bandwidth is better than 100 dB referred to a 3 Vrms
input. Larger inductors can be replaced by active inductors but
this reduces the signal-to-noise ratio.
