As engineers, you use many components and devicesevery day that you treat as black boxes. You are concernedonly about the inputs and outputs of the blackbox, and that approach is acceptable provided ...

PWM是Pulse Width Modulation的缩写，译为脉宽调制。 PWM是以方波为基波，用电平宽度表示信息的。PWM不改变基波频率，只是调制电平保持时间。因为方波只包含高、低两段电平，所以PWM常常做二进制调制。一般地，基波的高电平段被叫做“占”、On，而低电平段被叫做 ...
