Resolution and sampling rate are two important factors to consider when selecting an analog-to-digital converter (ADC). In order to understand these fully, concepts such as quantisation, and the Nyquist Criterion must be understood to a certain degree.

When an AC current flows through a conductor, outer filament of that conductor carries more current as compared to the filament closer to its center. This results in higher resistance to AC than to DC and is know as skin effect. Proximity effect, the alternating flux in a conductor is caused by the current of the other nearby conductor.

Pulse-width modulation can be of many forms. A PWM signal of constant frequency can be obtained by comparing the ramp signal (or carrier signal) with the error between the desired and the actual output voltage signal (Vc, compensator voltage signal).
