Now a days radio has become a common thing for every individual in the world. There has been many developments in radio after its invention in 1895 by Marconi. Particularly the concepts like cognitive radio and Software defined radio have been great advancements in communication. In this p aper we will explore the inner working of software defined radio with an in depth description of its inner structure and working. We wil l also deal with the internal block diagrams of SDR transmitter and receiver. Imagine a radio in which most of the operations are sof tware controlled, SDR brings this into reality by selecting modulation and demodulation frequencies using programmable devices like FPGA, DSP and ASIC. This SDR also provides signal enhancements (equalization) and filtering. Generally in S oftware D efined Radio every aspect of its operation is performed by controlling software. This paper on a whole gives an information regarding SDR transmitter and receiver.
