Latest Patents
Hollinden's latest patents include a "Television receiver with display driver amplifier and input video filter." This invention describes a television receiver that responds to broadcast signals in a normal operating mode. It features a television signal channel equipped with high-frequency peaking circuits, followed by a display driver that can accept an auxiliary video signal. A low pass filter is integrated between the output of the television signal channel and the display driver, which allows for a wide bandwidth when displaying auxiliary video information. The filter's bandwidth is inversely related to the bandwidth of the driver, ensuring optimal performance. Additionally, it exhibits a trapping characteristic at the second harmonic frequency of the chrominance signal in color television receivers.
Another significant patent is the "Plural input television receiver having peaking circuit and chrominance." This invention also responds to broadcast television signals and includes a video channel with high-frequency peaking circuits. It is designed to work with a wideband display driver that accepts auxiliary R, G, B color image signals in an auxiliary operating mode. The low pass filter in this design restricts the high-frequency response of the video channel in normal mode, preventing excessive signal bandwidth and unwanted spurious high-frequency effects.
