As the picture shows, it is a function generator circuit formed by 555 timer. This circuit is made up of a CH7555 timer, some transistors and RC components, which can generates triangle wave, square wave, sine wave, saw wave and swept wave. All kinds of wave have a adjustable frequency from 0.1 Hz to 100k Hz. The amplitude of vibration of square wave is from 5 V to 15 V which can drive TTL circuit. The accuracy of sine wave is higher than 3%.
