WB IQ, was it ever used after the CTC2/B
Still pondering the relative picture quality of the NTSC spec’ed WB IQ chroma demodulation used in the RCA CTC2/B chassis and the simplified NB R-Y B-Y chroma demodulation used in all other RCA CTVs thru 1980 at least. When did any CTV return to WB IQ if ever! My two premium Diamond-view Mitsubishis of 1988 and 1996 both have comb filters but I can’t identify WB IQ in either. Admittedly I have very few detailed schematics of my Sonys but both 1982 and 1992 jungle chips identify R-Y, B-Y demodulators, no mention of IQ anything. So does anyone know for sure any modern CTVs that for sure use WB IQ processing? My 1988 13in Sony RVM 1344 Pro Monitor must surely use WB IQ demodulators along with it’s comb filter, the direct screen is awesome. We’re there ever fully digital implemented CTV, AD rf inputs thru all digital demods to LCDs before the end of NTSC? How about the high-end ATSC to NTSC converter boxes that outputted component analog video or the best DVD players, did they encode MPEG to NTSC in WB IQ? It seems that NTSC spec’ed WB IQ started and ended with the RCA CTC2/B chassis, or am I wrong……..Tom
