A circuit philosophy is described for qualifying properly recorded tone bursts on tape recordings. More specifically, these bursts, recorded on a control track accompanying audio materials, are used to synchronize various events in a low-cost audio visual machine. The circuit checks three important parameters of each burst; amplitude, duration, and frequency, and displays the total of all correct bursts. A block diagram and design philosophy are covered.
