A computer signal compensation circuit

Abstract

The invention discloses a computer signal compensation circuit, which includes a signal input circuit, an operational amplifier calibration circuit and a voltage stabilization filter circuit. The signal input circuit receives an analog signal at the input end of a signal transmission channel for receiving signals from a computer control terminal. The operation The amplifier calibration circuit is divided into two ways to receive the signal input circuit and output the signal, one way is input into the non-inverting input terminal of the operational amplifier AR1, and the other is input into the switch circuit composed of the transistor Q2, the transistor Q3 and the transistor Q9, and the comparison processing of the operational amplifier AR3 is designed at the same time After the signal is input into the voltage stabilizing filter circuit, the final voltage stabilizing filter circuit uses a voltage stabilizing circuit composed of a triode Q6 and a voltage stabilizing tube D3, and at the same time designs a π-type filter circuit composed of an inductor L3, a capacitor C6, and a capacitor C7 to filter and output , can automatically calibrate the analog signal in the signal transmission channel for the computer-controlled terminal receiving signal, and improve the stability of the signal and the 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...
