Abstract: Reproducing kinescope with plural cathode electrodes and a common grid electrode, a kinescope driver amplifier arrangement is disclosed for supplying frequency selective video signal drive to the kinescope. The receiver also includes networks for providing wide bandwidth luminance (Y) and plural color (r, g,b) image representative signals containing low and high frequency components, as derived from a composite color television signal. High frequency components composite color television signal. High frequency componets (e.g., drived from the luminance signal) above a prescribed frequency are selectively processed in a grid signal path.

Abstract: The cascode amplifier includes a lower voltage small signal, common emitter amplifier transistor and a high volt. common base transister. An active load circuit comprising a transistor of like conductivity with respect to the common base and common emitter transistor is coupled between the collector of the common base stage and a source of operating voltage. A disconnect diode, interposed between the emitter of the load transistor and the collector of the common base transistor, is based to a non-conductive state under quiescent condition, voltage dependent current feedback is provided from the emitter of the load transistor to the base of the common emitter transistor.

Abstract: In a digital video signal processing system including an image displaying kinescope, a digital-to-analog signal converter (DAC) comprises a VMOS transistor arrangement with a gate electrode, a drain electrode from which output analog signals are provided, and plural source areas with associated source electrodes which receive input digital signals. The source areas are binarily scaled to reduce effective output capacitance and power consumption. The DAC is also suitable for directly driving a high level cathode electrode of the kinescope.

Abstract: In a video signal processing system including an image displaying kinescope and a kinescope driver stage, a version of signals processed by the driver stage and video output signals from the driver stage are combined to produce a resultant high frequency signal respresentative of high frequency components deficient in the video output signal. The resultant signal is applied to an input of the driver stage to compensate for the high frequency deficiency otherwise manifested by the video output signal.

Abstract: VIDEO AMPLIFIER INCLUDING AN A-C COUPLED VOLTAGE FOLLOWER OUTPUT STAGE of the Invention A video amplifier suitable for providing amplified image representative signals to an image reproducing device having a capacitive input impedance component comprises a first wideband amplifier stage which provides video signal voltage gain substantially greater than unity. A second wideband amplifier stage provides approximately unity video signal voltage gain and includes at least one amplifying device having input, output and common terminals. An output load circuit comprising at least first and second resistors is coupled in series relation between the output and common terminals. Direct coupling means are provided for supplying amplified video signals from the output terminal to the image reproducing device. Amplified signals are capacitively coupled from the first stage to the input terminal of the second stage. A further capacitor is coupled from the input terminal of the second stage to a junction between the first and second resistors of the output load so as to couple video signal excursions of a polarity tending to reduce conduction of the amplifying device to the output terminal and the load.
