Circuit for compensating computer signal

Abstract

A computer signal compensation circuit includes signal input circuitry, Operational Amplifier Calibration Circuit and Regulated Filter Circuit, the signal input circuit receives an analog signal froman input terminal of a signal transmission channel for signal received by a computer control terminal, the operational amplifier calibration circuit receives the output signal of the signal input circuit in two ways, within a noninverting input of an input op amp AR1, the other input transistor Q2, in a switching circuit composed of a transistor Q3 and a transistor Q9, at the same time, an operational amplify AR3 is designed to input the signal into a voltage stabilize filter circuit after comparing and processing the signals, at last, that voltage stabilize filter circuit adopts a voltage stabilizing circuit composed of a transistor Q6 and a voltage stabilizing tube D3, At the same time, a Pi-filter circuit composed of inductor L3, capacitor C6 and capacitor C7 is designed, which can automatically calibrate the analog signal in the signal transmission channel of computer control terminal, and improve the stability and efficiency of signal transmission.

Description

technical field [0001] The invention relates to the technical field of circuits, in particular to a computer signal compensation circuit. Background technique [0002] At present, with the continuous advancement of science and technology, computers have been favored by people since their inception. Nowadays, computers have changed people's lives, especially under the influence of today's computer big data, computers have completely facilitated people's lives. However The analog signal in the signal transmission channel of the computer control terminal receiving signal needs to ensure that during the transmission process, the signal potential is insufficient or is interfered with by other signals of the same frequency, resulting in signal distortion. In order to ensure the smooth operation of the computer, The analog signal needs to be automatically calibrated during transmission to prevent interference from other signals of the same frequency. [0003] So the present invent...
