Abstract
PURPOSE: To ensure the accurate waveform shaping at all times regardless of the fluctuation of the information signal transmitted, by securing an automatic control for the slice level via the detection output of the upper and lower edge levels of the start signal.
CONSTITUTION: The TV signal containing the multiplied information signals such as the static picture signals, etc. obtained through reception circuit 1 rceives correction 26 for the effect of the local shift and then compensation 28 for the phase to be applied to the subsequent circuits. In other words, the amplitude is made large via upper level detector circuit 31 and amplitude adjusting circuit 29 in case singal F is received (the DC level at the part of the information signal lowered with small amplitude). And upper level is corrected to U from R', and the pedestal clamp level is lifted up via lower level detecting circuit 32 and pedestal clamp circuit 30 to correct the lower level from l' to l. Thus, information signal A is featuring correct DC level and amplitude is obtained. Signal A then applied to slice circuit 33 and sliced with slice level S at nearly center position, thus obtaining the information signal of the accurate binary signal
