One of the lesser-known ways that camera manufacturers have been able to make digital cameras ever smaller and less expensive is by using in-camera software to correct for lens distortion on the fly.

Distortion comes in two basic classes: Linear distortion, which is not an oxymoron; and nonlinear distortion, which includes all other distortions except noise. Noise is quite another matter and is ...

When discussing electronic circuits, I often lock onto the circuit's magnitude characteristics. For example, we refer to filters as high pass, low pass, or band pass, which is a shorthand way to ...

Transmitting high-speed data over a cable or printed-circuit-board (PCB) path will significantly attenuate and distort the signal. Transmission paths are usually transmission lines that introduce ...
