The NRD-545 DSP receiver has all the quality expected from JRC. As well as a fine front-end performance it is further enhanced by integral DSP functions. The digital processing is performed by a special DSP microprocessor performs signal detection in all the modes. Other features include an RTTY demodulator, Exalted Carrier Selectable Sideband and remote control by PC. The digital IF filter, one of the DSP features, provides sharper characteristics than a crystal filter, thus allowing continuous bandwidth adjustment. All traditional crystal and mechanical filters that have previously determined the selectivity characteristics of receivers have been eliminated from this DSP receiver.
