audio pre-amplification 音频预放大
Compared with the exsiting systems, our design system has 15~30 expansion in the dynamic range. So sanmping pre-amplification and digital contrast hybrid technology can effectively expand the dynamic range of AGC system.
与既有系统比较,获得了动态范围15~30dB的扩大,充分证明了采样前级放大技术及数字对比技术的混合使用能有效扩大AGC系统动态范围。
