(Note 7) REC mode sync gate start time, release time (TRGB, TRGE) :

Input Copm. Sync to T29 and assume the sync gate start time (TRGB) as the time from which the signal at T12

attenuates until the signal at T29 rises and assume the sync gate release time (TRGE) as the time from which the

horizontal sync signal rises till the signal at T12 increases (Fig. 2).

(Note 9) PB mode sync gate start time, release time (TRGB, TPGE) :

Input Comp.sync to T29 and assume the sync gate start time (TRGB) as the time from which the siganl at T18

attenuates until the horizontal sync signal rises and assume the sync gate release time (TPGE) as the time from which

the horizontal sync signal rises until the signal at T18 starts increasing.
