因果周期信号卷积算法研究

Cause and Effect Cycle of the Signal Convolution Algorithm

研究两类因果周期信号卷积时域计算方法,导出两渐升信号卷积计算公式,具体给出因果周期方波信号、因果周期三角波信号的卷积算法和波形。研究发现,因果周期信号自卷积结果是渐升因果信号,在有限时段上的卷积结果仅由有限多个单位阶跃信号乘指数函数叠加组成。

Two types of cause and effect by studying the periodic signal in time domain convolution method of calculating the two gradually or signals derived convolution formula,the specific cause and effect cycle square wave signal is given,cause and effect cycle of the triangular wave signal and the waveform of the convolution algorithm. The study found that a causal periodic signal from the convolution result is a causal signal gradually or,in limited time on the results of the deconvolution is limited only by the number of unit step signal composed by superposition of exponential function.
