CAS 2789及CAS2789 C均为全数码的接收器,其内包括有调谐器、QPSK解调器及前向错误矫正编码器(For-ward Error Correction decoder)的功能。CAS 2789 C更备有一具微控制器,能作为独立解调组件使用。该插件接收源自低杂音部份
CAS 2789 and CAS2789 C are all-digital receivers that include the tuner, QPSK demodulator, and forward-error correction encoder. The CAS 2789 C also features a microcontroller that can be used as a standalone demodulator. The plug-in receives a low noise part
