Software-Defined Radio (SDR) Forum defines SDR technology as radios that provide software control of a variety of modulation techniques, wide-band or narrow-band operation, communications security functions (such as hopping), and waveform requirements of current & evolving standards over a broad frequency range.

In a nutshell, Software-Defined Radio (SDR) refers to the technology wherein software modules running on a generic hardware platform consisting of DSPs and general purpose microprocessors are used to implement radio fun ....etc

Software radio is an emerging technology, thought to
build flexible radio systems, multiservice, multistandard, multiband,
reconfigurable and reprogrammable by software. The flexibility of a
software radio system consists in its capability to operate in
multiservice environments, without being constrained to particular
standard, but able to offer, services of any already standardized
systems or future ones on radio frequency band. The presence of the
software defining the radio inter face necessarily implies the use of
DSPs to replace d ....etc

The DRM Signal is received by a commercial long, medium, short-wave (SW, MW, LW) front-end. Any front-end should be usable which can provide an IF of 12 kHz direct or with an adapter circuit. The bandwidth must be greater 10 kHz for normal transmissions and greater 20 kHz for transmissions with channel bundling. This signal is then fed into a standard soundcard. The soundcard must offer a sampling rate of 48 kHz. For output of the audio signal also a soundcard with a sampling rate of 48 kHz is required. If one sound card is used for sampling th ....etc
