Latest Patents
One of his latest patents is the "Multiburst Signal Generation." This invention describes a multiburst test signal generator and a method for using the generator's test signal to determine the frequency response characteristics of television video circuits with a high degree of accuracy. The design allows for one of the burst frequencies to be continuously enabled and made variable, while the other burst frequencies are disabled. The resulting continuous sine wave is applied to the circuit being tested, and its frequency is varied, with the output monitored using a conventional frequency counter.
Another notable patent is the "Residual Clamp Error Compensation Circuit." This apparatus is designed to match the blanking levels of two television video signals. When a vertical interval reference signal or any other signal, such as sync, is inserted into a program video signal, their blanking levels must be matched. The described apparatus achieves this by sampling the residual clamping error of a slow clamp on the program channel and adding it to the signal being inserted. This ensures that the noise, which would have been added to the program video, is instead added to the inserted signal, making it invisible in the television picture.
