Summary
The FMCS-1 provides a complete solution for the Analog portions of the FM signal.
The FMCS-1 combines the features and functions of an RF Amplifier, FM Demod, Stereo Demod, RDS Decoder, Two SCA Decoders, and FFT Spectrum Analyzer in one product.
Using state of the art DSP techniques all of the FMCS-1 processing takes place in the digital domain, this results in FM analog performance that was previously not possible.
