Define the software defined radio, Electrical Engineering

Software Defined Radio (SDR) is an advanced radio technology in which flexibility is achieved in using radio functions such as modulation and demodulation of radio signals are carried out exclusively by use of different software running on a reconfigurable hardware. Just by downloading new software, SDR can reconfigure and upgrade to new standards. SDR does not change hardware components.

SDR is a radio communication transceiver system in which all the typical components of a communication system such as mixers, modulators/demodulators, detectors, amplifiers are implemented through software rather than hardware. Thus, the system is compatible with various communication standards by upgrading software on same hardware platform.

SDR  system is ideally expected to  tune  to any  frequency  band  and  receive  any modulation  across  a large frequency spectrum by means of a programmable hardware which is controlled by software.
