Variable bandwidth luminance filter with commonly tuned delay and amplitude controlling filters providing frequency independent and bandwidth independent delay characteristic |
摘要 |
A luminance signal filter for use in a multi-source television receiver, includes a tunable filter responsive to a bandwidth control input signal for determining the bandwidth of luminance signals applied to said filter and a variable delay circuit inversely responsive to said bandwidth control input signal for providing a substantially uniform overall delay for said luminance signal filter.
