A New Twist on the Software Defined Radio

Software defined radios (SDR) are not a novel concept; the original concept of a software radio first appeared thirty years ago. Due to the high cost of SDR hardware, though, software radio platforms really haven't been available as 'consumer' devices until recently. The wide availability of software defined radios for students, engineers & scientists, and hobbyists, was really kicked off by Matt Ettus in 2004. Since then, the use of the software defined radio has proliferated through many fields of communications and electronics.
