Signal generator in teaching, testing, monitoring and control, and other fields have a very wide range of applications, but with modern electronic communication technology, often require high precision and can easily adjust the frequency signal generator.
The design of direct use AT89C51 SCM as an important component of the wave generator, coupled with clever software design and simple external circuit, a frequency, adjustable rate sine, triangle, square and sawtooth, and other signals. Signals in the frequency and amplitude, directly through the keyboard input, and the LED display. And various types of existing waveform generator comparison, ATMEL the AT89C51 is a highly efficient microcontrollers, the small number of signal interference, output stability, high reliability, in particular the operation of simple, low cost, very suitable for physics experiments Room teaching and experimental use.
