| | Definition: | | A measure of the quality of reproduction of various frequencies (audio and video) by a circuit or device. If the frequency response of a video processor is adequate, there is no deterioration in image quality at the bandwidth extremes. For video, the NTSC broadcast bandwidth is 4.2 MHz and the PAL broadcast bandwidth is 5.5 MHz. For audio, full bandwidth implies a frequency response extending from 20 Hz to 20,000 Hz or higher. |
