Furthermore, the expression of stationary bit error rate of system output corresponding to equiprobability quaternary pulseamplitude modulation (PAM) input signals was deduced.
给出了当输入信号为等概率的四进制脉冲幅值调制（PAM）时，系统输出理论渐近误码率计算公式。

Change the inverter output voltage or output current are two kinds of different ways, namely, PAM pulseamplitude modulation 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。

The Fourier transform method has been used to analyze the influence of modal amplitude and phase fluctuations in a mode-locked laser on performance of its outputpulse.
