ABSTRACT:
A system is provided for controlling the intermediate frequency passband response of a television receiver in response to a vertical interval reference (VIR) signal. The baseband VIR signal includes a chrominance reference bar signal component and a luminance reference level signal component. The amplitudes of these two signal components are detected and differentially compared to develop a control signal indicative of the ratio of the two detected signal components. A passband shaping circuit included within the intermediate frequency signal processing section of the television receiver is responsive to the control signal for dynamically adjusting the amplitude versus frequency response characteristic of the intermediate frequency signal processing section as a function of the ratio indication control signal.
