DSP-based demodulation provides a receiver with great flexibility, where
additional modes can be easily added by a simple software change, while the
hardware remains the same. Plus of course, there is a benefit of performance
consistency: With the same input, a software routine will always produce the
same result, not depending in variations and aging of components such as
diodes, resistors and capacitors.
Another advantage of this concept is in the ability to present the IF signal in a
real-time spectrum display. Being able to “see” a signal and its neighborhood,
in addition to merely hear it, has brought about a major paradigm change and
increased a radio operator’s expectation as to what to expect from a radio
receiver.
