ABOUT THE SDR WIDEBAND RECEIVER CIRCUITS While ordinary wide band receivers need to have dedicated demodulator circuits for each receive mode, the ICR8600 utilizes advanced digital processes that demodulate the incoming signals. The IF signal is sent to the A/D converter, resulting in digital signal, then is processed by a high-speed FPGA and DSP to be restored to an analog audio signal. The received signal is processed to be demodulated according to the receive mode, including not only conventional analog communications in CW, AM, SSB, FM, WFM and FSK, but also advanced digital communications in D-STAR, P25, NXDN, dPMR and DCR.
