modulation that imposes a signal on a train of pulses
双语例句
1
This controller integrates pulse width modulation(PWM) and pulse density modulation(PDM) together, and can easily change between the two modulations.
该设计集成了脉冲宽度调制(PWM)和脉冲密度调制(PDM)两种调制方式,并可以在两者间切换。
2
The simulations show that more amplitude modulations and phase perturbations lead to lower contrast of the compressed pulse, and bigger modulation cycle results in wider pre-pulse width.
