ccir 624 Abstract: filter ccir 624 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,	Original	PDF	FP443A FP443B FP358C DR00020B FARA161d Dec-99 ccir 624 filter ccir 624
Untitled Abstract: No abstract text available Text: FF….M SERIES LOW PASS VIDEO FILTER STEEPNESS FACTOR 1.14 This range of Elliptical Function Low Pass filters is intended for bandwidth limitation where a fast rate of cut off is required. It is especially useful in removing sound sub-carriers from a video signal while maintaining essential	Original	PDF	FF0200M* FF0250M* FF0300M* FF0350M* FF0400M* FF0450M* FF0500M* FF0550M* FF0580M* FF0600M*
RFR1772S Abstract: No abstract text available 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	Original	PDF	DR00020B FARA158d Dec-99 RFR1772S
Untitled Abstract: No abstract text available Text: FF….L SERIES LOW PASS VIDEO FILTER STEEPNESS FACTOR 1.35 These low pass video filters are intended for bandwidth limitation over the video range of frequencies. The filters are 7-pole Elliptical Function networks which have been equalised to correct for group delay distortion over 95% of the	Original	PDF	FF0200L* FF0250L* FF0300L* FF0350L* FF0400L* FF04rformance DR00020B FARA170d Dec-99
Untitled Abstract: No abstract text available Text: FF….P SERIES LOW PASS VIDEO FILTER STEEPNESS FACTOR 1.14 These low pass video filters are intended for bandwidth limitation over the video range of frequencies where it is required to attenuate frequencies close to the edge of the passband.
