设定一个信息码串，产生常见的编码如单极性非归零、双极性非归零、单极性归零、双极性归零、AMI、HDB3码的时域波形；

不考虑噪声影响，以采样电平为依据恢复出原始信息串。-Set up an information code string to produce a common code such as the unipolar NRZ, bipolar, non-zero, zero unipolar, bipolar zero, AMI, HDB3 code in time domain waveform　not consider noise impact to sample level as the basis to restore the original information out of string.
