Furthermore, the expression of stationary bit error rate of system output corresponding to equiprobability quaternary pulse amplitude 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。

The structure of grinding wheels can realize high point grinding, and the good grinding equiprobability lies on a proper spinning speed and the random variation of the spinning axis.
