分析了在解码电路实验中，测量波形产生误差的原因，提出了采用有线电视系统传送信号的实验方法。
This paper analyzes reason of measure waveform produce error in decode circuit, put forward experiment means of adopt closed circuit television system transmit signal.
如果不进行“调零”修正，所产生的偏置量就会叠加到输入信号上产生误差。
Unless it's corrected by "zeroing," the resulting offset produces an error by adding to the input signal.
如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured.
