Abstract

The invention relates to a program-controlled triangular wave generation system, comprising a trigger, a controller, a digital-to-analog converter and a low-pass filter with a signal output port sequentially connected through signal ports, wherein the controller is connected with a computer terminal through signals; the controller comprises a phase accumulator, a single chip microcomputer, a reference clock module and a waveform memory all connected with the phase accumulator through signals. As the single chip microcomputer is adopted as the control part, the problem of high cost caused by the red programmable digital device of the prior art is avoided, the low cost of the system is realized, and the frequency and the amplitude of the triangular wave are controlled by a trigger, so that the triangular wave generation system can be debugged more conveniently; at the same time, by setting the reference clock module and the phase accumulator, the waveform is accumulated and the stabilityof waveform is improved.

Description

technical field [0001] The invention relates to a triangular wave generating system, which belongs to the technical field of electronic signal equipment. More specifically, the invention provides a program-controlled triangular wave generating system. Background technique [0002] Triangular Wave, also known as sawtooth wave, refers to the waveform that is mainly used in the scanning circuit of CRT as a display device. [0003] Triangular waves are widely used in anti-shock design, radar ranging, and other electronic equipment. The existing triangular wave generating circuit for generating triangular waves is divided into a small system built with analog and digital devices. For analog systems, the devices used are complex, which is not convenient for debugging and setting during use, and it is easy to cause the waveform of the triangle wave to be unstable; for digital systems, programmable digital devices are used, resulting in high cost. It is necessary to increase the c...
