Part 1 gave a general description of digital signal processing (DSP) in software-defined radios (SDRs).1 It also provided an overview of a full-featured radio that uses a personal computer to perform all DSP functions. This article begins design implementation with a complete description of software that provides a full-duplex interface to a standard PC sound card.
To perform the magic of digital signal processing, we must be able to convert a signal from analog to digital and back to analog again. Most amateur experimenters already have this capability in their shacks and many have used it for slow-scan television or the new digital modes like PSK31.
