| Abstract: | This arcticle introduces the design of the system and the principle of the low frequency waveform generator which is based on a microcontroller and is adopted the technique of phase locking. The generator can produce accurate sine, square, triangle and sawtooth waveforms. The frequency and the voltage amplitude can be adjusted convenientely with a good stability. |
