Abstract
Signal generator is a kind of can produce much waveform, such as triangle wave, square wave, sine wave circuit. Signal generator in the circuit experiment and test equipment in a very wide range of purposes. The design of the principle of the signal generator and structure analysis, design of sine wave-square wave-triangle wave simple signal generator. Design of the first set by a dc voltage circuit scheme: power supply circuit, venturi oscillator,parator, posed; Then each unit circuit of the principle is analyzed by dc stabilized voltage power supply circuit, provide the voltage required, venturi oscillator produce sine wave, parator produce square wave, integrators produce triangle, and at the same time in the circuit to wave the parameters of ponent w
