Pulseamplitudemodulation (PAM) is one form of the ways, in which it is widely used in the system of communication and control.
脉冲幅度调制波（PAM）是脉冲调制的一种形式，在通信和控制系统中得到广泛应用。

Change the inverter output voltage or output current are two kinds of different ways, namely, PAMpulseamplitudemodulation control and PWM control pulse width modulation.
改变变频器的输出电压或输出电流有二种不同的方法，即PAM脉冲幅值调制控制和PW M脉冲宽度调制控。

Furthermore, the expression of stationary bit error rate of system output corresponding to equiprobability quaternary pulseamplitudemodulation (PAM) input signals was deduced.
