Design of Signal Separation Device Based on STC89C52 Microcontroller
This paper describes the design of a signal separation device,which is based on stc89c52 single chip microcomputer,composed of adder module,MAX262 program control filter module.A set of signal separation device is designed.The gain of the adder with LM358P as the core is 1,which can realize C=A+B;Using MAX262 program control filter to achieve the filtering function,signal A and B are sine waves,the frequency of 10kHz integer multiple,the device can correctly separate signals A'and B',and the peak value is not less than 1V.After testing,it can be confirmed that the display waveform of the device is undistorted and stable.
