analog back-up

A receiving device then converts the digital signals back to analog using audio decompressor, playback.

使用音频减压装置, 放音的,接受设备然后转换数字信号回到类似物.

Improvement of Back Logic Circuit of IC Test System and Research of Analog Delay Line Capability

集成电路测试系统后逻辑支持电路改进与模拟延迟线性能分析

Analog Loop Back is a common test for locating transmission problems in data transmission systems.

数据传输系统中,模拟环回是一种常用的测试本地传输状况的方法.

Analog front-end circuit consists of preamplifier, low pass filter circuit and back stage amplifier circuit, preamplifier circuit instrumentation amplifier is used because it has a high input impedance, high common mode rejection ratio ( CMRR), low noise, and low drift.

模拟前端电路由前置放大电路、高低通滤波电路和后级放大电路组成，前置放大电路用的是仪表放大器，因为它有高输入阻抗、高共模抑制比（CMRR）、低噪声、低漂移。

And check the analog gauge and yellow-glow back lighting.

并检查模拟评估和黄色辉光返回照明.
