Low frequency signal generator can be used to measure the sensitivity, frequency response, frequency compensation and tone control of amplifier circuit. It also can be used to repair low frequency amplifiers. So it is a very useful measuring instrument. It also can be used as signal source of digital clock. According to the practical needs, the user can choose from 8 fixed frequencies output by the signal generator. The output amplitude is divided into two gears: 0 ~ 0.1 V, 0 ~ 1 V which can be adjusted continuously. Principle of the circuit is as shown in the figure. Integrated circuit CD4060 is a 14-level frequency divider installed with oscillator.
