Multi-Signal Generator Design

Signal generator is electronic equipment which can produce standard signals, and it often is used in industrial production electronic laboratories and the electronic equipment. Signal generator can achieve in a variety of methods, and the higher frequency and the more waveform is the better the signal generator condition. We can consider its implementation from the production and using areas. This paper will use function in the external circuit chip ICL8038 and electronic way to produce triangle wave, sine wave, rectangular wave,which are three basic rectangular waveforms, then the wave through ICM7216D, crystal, capacitors, switches and LED digital which are composed of the circuit to show the frequency and makes the sine wave produce a frequency modulation wave through FM circuit.
