Text: GROUP DELAY PRE-CORRECTION The specifications for a number of television systems state that the transmitted signal must be precorrected in terms of group delay to allow for the distortion produced by the IF filters in television receivers. CCIR Rep.624 recommends three curves which apply variously to the following systems: B/PAL,

Text: RFR SERIES ANTIALIASING FILTERS These filters are designed especially for use in systems where composite video signals are digitised. A sampling frequency of four times the colour subcarrier frequency is normally used as with D2 systems. The filters have a bandwidth of 5.5 MHz for
