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

模拟过采样调制器还可以应用于处理音频信号的D类率放大器中。

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.

双回转构的步控制路由TDA1521音频率放大器组平衡桥式率驱动路，由计算并行口经过锁存器构脉冲分配器。

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，鉴于模拟路设计中涌现的巨大创造力，分立率放大器的设计显得相当缺乏新意。
