In the work of scientific research and test of equipment, some signals with fixed or variable frequency are usually needed. To reduce the cost, single chip and some simple peripherial components are used in the design to produce the signals with the needed frequency, at the same time to complete the measurement of frequency. The application results show that, with the advantages of simple principle and operation and stable performance, the digital signal generator can better satisfy the need of scientific research experiment.
