Digital signal processing is often a mystery to many people, but the underlying principles are fairly straightforward and within the grasp of anyone with a technical background. In this feature, we’ll ...

A signal-to-noise ratio (SNR) lets us express the relationship between signal and noise powers, as well as between the root-mean-square (rms) values of signal and noise voltages: SNR (dB) = ...

Age exposure alert! I have a textbook — a very good one I might add — from my undergraduate studies of communication systems called: Modern Digital and Analog Communication Systems. From this, and as ...

The electronic digital signal processor drives the present information age, allowing a seamless interaction between our information-rich analogue world, and the digital domain of the microprocessor.
