FCC Federal Communications Commission. The U.S telecommunications regulator, an Independent agency of the American Government which regulates all non-federal government use of the radio spectrum (including radio and television broadcasting), all interstate telecommunications (wire, satellite and cable), as well as all international communications that originate or terminate in the United States.
Fiber Optics Refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fiber. Optical fiber carries much more information than conventional copper wire and is in general not subject to electromagnetic interference and the need to retransmit signals. The signal loss in a fiber optics system is usually smaller than in coaxial cables, and so optic fibers are often used to carry signals over extremely long distances.
Fixed Pixel Displays Display technologies such as LCD, Plasma and DLP that use an non-fluctuating matrix of pixels with a set number of pixels in each row and column. These display devices have actual pixels (picture elements) that make up the display. With such displays, adjusting (scaling) to different aspect ratios because of different input signals requires complex processing. In contrast, the CRT electronics architecture "paints" the screen with the required number of pixels horizontally and vertically.
Frequency Modulation When a low frequency signal modulates (changes) the frequency of an RF signal of a much higher frequency (causing it to move around the basic carrier frequency) - the process is called frequency modulation or FM. This system is extensively used in broadcast radio transmission, as it retains high signal quality.
Frequency Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency.
FLAC Free Lossless Audio Codec (FLAC) is an audio codec audio data compression. FLAC accomplishes data compression without sacrificing the integrity of the audio source, since it does not discard any part of the data. A digital audio recording (such as a CD track) converted by FLAC can be decompressed into an identical copy of the audio data. Audio sources encoded to FLAC are typically reduced to 50–60% of their original size
