A Nyquist filter is a filter used in TV receivers to equalise the video characteristics. The filter is named after the Swedish US engineer Harry Nyquist (1889 1976).In analogue TV broadcasting the visual radio frequency (RF) signal is produced by amplitude modulation (AM) ; ie, the video signal (VF) modulates the carrier. In AM two symmetric sidebands appear , each containing identical information. So the RF bandwidth is two times the VF bandwidth. For example, the RF bandwidth of a VF signal with a bandwidth of 4.2 MHz, is 8.4 MHz. (System M) In order to use the broadcast band more efficiently, one sideband can be suppressed. However, it is impossible to suppress one sideband completely without affecting the other. Furthermore, a very sharp edge filter characteristic causes untolerable delay problems. So as a compromise, a standard filter is used which reduces a considerable portion of one side band without causing extensive delay problems. Such a filter is known as vestigial side band filter (VSB).
