Design and simulation of non-sinusoidal wave signal generator based on Multisim

Rectangular wave,triangle wave and sawtooth wave are collectively referred to as non-sinusoidal wave in the electronic circuit. The non-sinusoidal signal generator designed in this paper is based on a rectangular wave generating circuit. It can generate triangle wave or sawtooth wave by adding an integral circuit and auxiliary circuit at its output end. The signal ampli-tude,frequency and duty ratio can be controlled by designing the auxiliary circuit. This circuit was built and analysed in the Multisim 10 development environment. The results show that the circuit meets the design requirements and can realize the ex-pected function.
