Digital AM FM signal Processor

General Description:
The TDA7500 is an integrated circuit implementing a fully digital, integrated and advanced solution to perform the signal processing in front of the power amplifier and behind the AM/FM tuner or any other audio sources. The chip integrates two 43 MIPs DSP cores: one for stereo decoding noise blanking, weak signal processing and multipach detection and one for sound processing.
