The deta-sigma ADC is composed of analog deta-sigma modulator and decimator.

模拟过采样调制还可以应用于处理音频信号的D类功率放大。

To control stepping motors, the balance bridge power drive circuit is made up by TDA1521 integrated audio power amplifier, the pulse allotter is made up by the parallel ports of computer and latches.

回转机构的步进电机控制电路由TDA1521音频集成功率放大组成式功率驱动电路，由计算机并行口经过锁存构成脉冲分配。

Sometimes it is said that discrete power amplifier design is rather unenterprising, given the enormous outpouring of ingenuity in the design of analogue ICs.

有时人们会说，鉴于模拟集成电路设计涌现的巨大创造力，分立功率放大的设计显得相当缺乏新意。
