Computer signal automatic correction circuit

Abstract

A computer signal automatic correction circuit is disclosed, including signal input circuitry, a logarithmic calibration circuit and a regulated output circuit, the signal input circuit receives an analog signal from an input terminal of a signal transmission channel for signal received by a computer control terminal, the logarithmic calibration circuit receives an output signal of a signal inputcircuit in two paths, one path is input to a noninverting input of an input operational amplifier AR1, The other path is input to a logarithmic circuit consisting of an operational amplifier AR2 and atransistor Q2. At that same time, an operational amplify AR4 and an operational amplifier AR5 are designed, a differential comparison circuit composed of an operational amplifier AR6 performs a differential comparison process and then inputs the output a regulated voltage output circuit, which stabilizes the output signal of the operational amplifier AR1. At last, the regulated output circuit adopts the voltage stabilize circuit composed of the transistor Q6 and the voltage stabilizing tube D3 to output the voltage stabilized signal. The circuit can automatically calibrate the analog signal in the signal transmission channel for the signal receive by the computer control terminal, thereby improving the stability of the signal and the efficiency of the signal transmission.
