A typical software defined radio consists of the following components. A receiving RF preamp feeds directly into a very fast A-to-D converter which is connected to a computer DSPCPU to tune a signal and extract the modulated audio or data. Mixers filters amplifiers modulatorsdemodulators detectors etc are instead implemented by means of software on a personal computer or embedded system.
