Latest Patents

One of his latest patents is titled "System for, and method of, processing quadrature amplitude modulated signals." This invention addresses the challenges of processing analog signals encoded with QAM as they pass through coaxial cables. The system utilizes a variable frequency oscillator to produce intermediate frequency (IF) signals, which are then converted to digital signals by an analog-digital converter (ADC). The digital signals are demodulated to create two signals with a quadrature phase relationship. The invention includes a symmetrical equalizer that combines feed forward and decision feedback equalizers to eliminate noise and distortions from the coaxial cable. The system also features servos that adjust the oscillator frequency, ADC sampling clock, and gain to ensure optimal performance.
