According to the waveform control system disclosed by the invention, a direct current power supply VCC is directly converted to a square wave signal, the amplitude value and frequency of the square wave signal at the output end can be changed by changing the size of the power supply VCC and the charge and discharge frequency of a capacitor C1, the secondary amplification is not required, high stability can be achieved, and the obtained waveform is low in distortion rate.

Description

technical field [0001] The invention relates to a control system, in particular to a waveform control system. Background technique [0002] In analog electronic circuits, signals of various waveforms are often required, such as sine wave, rectangular wave, triangle wave and sawtooth wave, etc., as test signals or control signals, etc. The laboratory often converts these waveform signals to obtain other waveforms. However, the existing sine-to-square wave waveform conversion circuit has a narrow range of input signals, and the amplitude of the output square wave signal is uncontrollable, which is inconvenient to use. It is necessary to re-amplify the output square wave signal, which can easily lead to Signal distortion. Contents of the invention [0003] The purpose of the present invention is to provide a waveform control system to solve the problems raised in the background art above. [0004] To achieve the above object, the present invention provides the following tec...
