- In this example, cosine of uniform random matrix multiplied by a triangular time varying standard deviation as noise, and Sinc pulse time varying as a base band signal are summed to form a PM signal. 本例以均匀随机变数矩阵之馀弦乘以标准差为三角波时变代表杂讯，及时变滤波函数脉波代表基频讯号，合成基频讯号及杂讯和之相位调变讯号。
- By a moving single period sine wave model, the instantaneous frequency of the signal is obtained, and then, by the integral of the instantaneous frequency, the PM signal wave is demodulated. 在调制信号是方波的情况下，给出了相位解调的仿真结果和其它参数的波动情况；
