Software Defined Radio (SDR) – Part 1

Software Defined Radio (SDR) is a radio communication system where majority of signal processing units such as modulation, demodulation and signal filtering modules were implemented by means of a software in a computer whereas a traditional radio communication system uses dedicated hardware modules to perform such operations.

Typical SDR system may consists of a computer, audio processing device and an RF module to receive and/or transmit radio frequency.

Before we go into details let’s understand basic concepts of an SDR. 

Up coming articles, let’s discuss on listing to aviation communications using SRD followed by tracking an aircraft.
