Combination of CA3130 and CD4010 ICs provides broad fre-quency response at very low power levels, as required for driving frequency counter. Diodes protect input from overvoltage. Amplifier offset control pot is used as trigger level control. Input sensitivity of amplifier/trigger combination is 50 mV P-P from 1 Hz to 1 MHz.-R.
