CLIPPER (or LIMITER) 1 & 2
Two independent CLIPPERs are provided which will amplify any analog TIMS level signal and
then clip or limit the amplitude of the amplified signal to a preset level. Each clipper’s output
level can be preset by a PCB mounted continuously variable gain control, GAIN 1 and GAIN 2.
33.3kHz BPF
The 33.3kHz bandpass filter is a 6th order filter with a 6kHz passband. The BPF accepts and
outputs standard TIMS level signals.
