摘要:A monolithic semiconductor integrated circuit for television receivers includes a video intermediate-frequency amplifier circuit, a video detector circuit and a sync separator circuit. The video intermediate-frequency signals are fed to said video intermediate-frequency amplifier circuit via an externally located input terminal of the integrated circuit. The sync separator circuit sends sync separator output signals to an output terminal of the integrated circuit. A low-pass filter is specifically connected between said output terminal of the integrated circuit and said sync separator circuit. The time constant of the low-pass filter is so selected that the pulse width of the sync separator output signals obtained from said output terminal is nearly equal to the pulse width of horizontal sync pulses in the composite video signals and that harmonic components in the horizontal sync pulses are reduced.
