In electronics and electrical engineering, the form factor of an alternating current waveform (signal) is the ratio of the RMS (root mean square) value to the average value (mathematical mean of absolute values of all points on the waveform). [1] It identifies the ratio of the direct current of equal power relative to the given alternating ...
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. [ 1 ] [ 2 ] A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard.
Form factor (quantum field theory), a semi-empirical formula used in effective quantum field theories; Atomic form factor, or atomic scattering factor, a measure of the amplitude of a wave scattered from an isolated atom; Electric form factor, the Fourier transform of electric charge distribution in space
One method of DC-to-DC conversion first converts power to AC (using a device called an inverter), then uses a transformer to change the voltage, and finally rectifies power back to DC. A frequency of typically several tens of kilohertz is used, as this requires much smaller inductance than at lower frequencies and obviates the use of heavy ...
A method of regulating generators so that multiple units share the load proportional to their ratings. dual control theory A branch of control theory that deals with systems whose characteristics are initially unknown. dual loop A method of supervising contacts and wiring in a security system, so as to detect some faults or tampering.

The Fourier transform of a periodic function cannot be defined using the integral formula directly. In order for integral in Eq.1 to be defined the function must be absolutely integrable. Instead it is common to use Fourier series. It is possible to extend the definition to include periodic functions by viewing them as tempered distributions.
L.A. had the option to attempt a free kick after the fair catch. It was the rare instance in which it made sense because no time remained on the clock.
In this case the periodic variation is a variation in the insertion loss of the network against increasing frequency. The variation may not be strictly linearly periodic. In this meaning also, ripple is usually to be considered an incidental effect, its existence being a compromise between the amount of ripple and other design parameters.
