60Hz Clock Generator This circuit is connected to the 120vac power line and transfers 60Hz
clock pulses to a logic circuit. The opto-isolator used provides 5000
volts of isolation between the power line and the logic side of the
circuit
Wide Band
Zero Cross Detector This circuit was designed to convert a low amplitude 40KHz signal into
a clean square wave signal. It will work with inputs as small as 5mv
peak-to-peak or as large as 3 volts peak to peak. The input
frequency can range from a few kilohertz to about 150KHz.
