Electronic component for decoding of a radio transmission channel carrying digitally coded information, especially for digital satellite broadcast

摘要

The frequency channel decoding method has a monolithic integrated circuit with a synthesizer module. The input signal (ES) passes to an analogue block (BAN) for down conversion and filtering. A phase and quadrature signal with information pass to Analogue to Digital conversion channels (CAN1,CAN2). The output passes to a digital module (DM) and is demodulated and filtered to remove adjacent channel information and providing the information output (FM).
