本文所设计的数字脉冲宽度调制器采用CMOS工艺，适合于不同的语音合成集成电路。
The digital pulse width modulator adopts CMOS technology and is suitable for a variety of speech synthesis integrated circuits.
为了实现这种控制策略并把脉冲宽度调制(PWM)波送到相应的开关，采用了数字信号处理技术(dsp)和通用逻辑阵列技术(GAL)。
In order to implement this strategy and deliver the PWM pulses to the appropriate switches, digital signal processor (DSP) and generic array logic (GAL) are used.
