Soft­ware-defined radio (SDR) is a radio com­mu­ni­ca­tion sys­tem where com­po­nents that have been typ­i­cal­ly imple­ment­ed in hard­ware (e.g. mix­ers, fil­ters, ampli­fiers, modulators/demodulators, detec­tors, etc.) are instead imple­ment­ed by means of soft­ware on a per­son­al com­put­er or embed­ded sys­tem. While the con­cept of SDR is not new, the rapid­ly evolv­ing capa­bil­i­ties of dig­i­tal elec­tron­ics ren­der prac­ti­cal many process­es which used to be only the­o­ret­i­cal­ly pos­si­ble.  This enables easy sig­nal pro­cess­ing and thus cheap wide band scan­ner radios to be pro­duced
