产生固定周期数的正弦脉冲信号 使用该函数时必须预先设定如下参数：正弦波的频率Fp，构成输出脉冲的正弦波的周期个数Nc，脉冲幅度A每个周期的采样点数smp。函数有两个输出：脉冲波形，以响亮sinpulse的形式输出，采样周期dt。(Produce a fixed number of cycles of the sine pulse signal         Use this function must be pre-set the following parameters: a sine wave of frequency Fp, constituting the output of the pulse cycle of the sine wave of the number Nc, the sampling points for each cycle of the pulse amplitude A smp. The function has two outputs: output pulse waveform, the a loud sinpulse form, the sampling period dt.)
