The multi-purpose signal generator circuit is composed of the integrated circuit oscillators and the frequency dividers, it produces the square wave from the high frequency to the sub-audio frequency, and it also produces the frequency standard VHF. The alternative oscillator part feeds the signal back to the 10-frequency divider stage. The extra SN7490 frequency divider can connect into the points of the frequency divider to add the 5 frequency division and 2 frequency division functions. The light-emitting diode of the 1MHz crystal stage indicates that whether the circuit is oscillating. The second stage can use any external crystal, the operating frequency is in the VHF low frequency range.
