Latest Patents

One of his latest patents is a stochastic demodulator for phase jump-modulated signals. This innovative demodulator features a multiplexer connected to different transmission channels. The output of the multiplexer is linked to a sampler-coder, followed by an interpolator, which is then connected to a phase jump converter and a statistical decision device. This device validates the code conversion result when a certain number of samples taken in a series of successive samples exhibit a phase jump within the same range of values. Another significant patent is a binary word processing method using a high-speed sequential adder. In this method, the words to be added together by the high-speed sequential adder are stored in shift registers. The serial outputs of these registers are connected to the corresponding inputs of a transcoder, which produces the binary number of '1's for each bit weight of the words to be added. This value is sent to an adder-divider that adds it to the number of carried '1's' from the immediately lesser weight and divides this sum by two. The fractional part of this half-sum is sent to an output register, while the whole-number part is directed to a carry register. This method has applications in digital filters for PCM telephone switching.
