Problems solved by technology

[0002] At present, computer equipment mainly includes a control terminal, a signal transmission module, a data processing module and a cloud. The data processing module processes and modulates the data information, and sends it to the cloud through the signal transmission module. The cloud and the control terminal exchange information through the signal transmission module. Since the signal in the signal transmission channel for exchanging information between the cloud and the control terminal is prone to interference from power plants or urban high-frequency signal towers during long-distance transmission, when the signal passes through such equipment during transmission, it will Make the signal frequency abnormal, resulting in harmonics in the signal, which in turn leads to a large error in the low-frequency data signal received by the controller in the computer equipment

Abstract

The invention discloses a data signal distortion adjusting circuit. The circuit comprises a frequency acquisition circuit, a feedback calibration circuit and a voltage stabilization output circuit, wherein the frequency acquisition circuit acquires a low-frequency data signal received by a controller in the computer equipment; the feedback calibration circuit uses an operational amplifier AR1 anda capacitor C2 to form a noise reduction circuit, low frequency signal noise is filtered, one path of an output signal of the noise reduction circuit uses an operational amplifier AR2, a diode D2 anda diode D3 to form a detection circuit to filter a disturbance signal in the signal; in the second path, a triode Q4 and a triode Q5 form a push-pull circuit to prevent signal crossover distortion; and finally, the operational amplifier AR3 adds the two paths of signals and inputs the signals into the voltage stabilization output circuit. The voltage stabilization output circuit uses an operational amplifier AR4, an operational amplifier AR5, a capacitor C4 and a capacitor C5 to form a filter circuit to further stabilize signal potential output, and error correction can be carried out on low-frequency data signals received by a single-chip microcomputer port in a controller in computer equipment.
