ZHC358D Digital FM Demodulator
Introduction:
This digital FM demodulator is a professional FM broadcasting radio receiver. It is the innovational FM radio demodulator which has a digital audio output AES/EBU. It can be used with a digital FM transmitter or a digital FM modulator to achieve high-quality FM transposer. It can also be used for high-quality receiving and remote monitoring of the FM radio signal.
Overview
ZHC358D FM demodulator is a high-quality broadcasting radio receiver. It has sensitivity for receive. The output of audio signal can be displayed on LCD. It has digital audio AES/EBU output and standard communication interface for telemetry. It can be used for radio broadcast transposer , multi-channel FM signal monitoring and any other occasions where multi-channel and high-quality is required.
This product uses the latest DSP processing receiver IC, while high-quality FM demodulation, it can detect and display each receiving channel’s field strength values, the RF signal SNR, stereo status, output audio level etc. at the same time. These parameters can be read by other hosts through the communication interface.
