微机接口电路的噪声抑制

THE NOISE REDUCTION OF INTERFACE CIRCUIT OF MICROCOMPUTER

本文阐述了在微机接口电路中,模拟信号及数字信号的噪声抑制和抗干扰问题。并以实例说明放大电路、A/D转换电路的噪声抑制和补偿方法;最后,讨论了接口电路中最佳抗干扰编码及调制方式。

This paper illuminates analogue signal and digital signal is noice reduction and interference-free problem in interface circuit, If also cites instances in illustration of noise reduction and compensation method of amplifer circuit and A/D converter circuit. At last. it argues the best interference-free code and mode of modulation in interface circuit.
