Title: The Innovations of Robert A. Hawley
Introduction
Robert A. Hawley is a notable inventor based in Tustin, California. He has made significant contributions to the field of electronics, holding a total of 7 patents. His work primarily focuses on developing advanced filtering and modulation techniques that enhance signal processing.
Latest Patents
One of his latest patents is the NTSC interference rejection filter. This invention is an electronic, programmable filter designed to selectively remove interference, noise, or distortion components from a frequency band without affecting other signals within that band. The filter operates by initially demodulating an input frequency band, such as a television channel spectrum, to baseband. It then combines the baseband spectrum with a synthesized frequency signal to shift the spectrum, allowing for the removal of interference components around DC. The resulting spectrum is mixed back to its original representation, optimizing the filter response for various interference components.
Another significant patent is the variable rate modulator. This invention introduces clock signals and digital data signals at a variable frequency to a FIFO, which are then passed at a second frequency controlled by a numerically controlled oscillator. The phases of the clock signals are compared with those from the oscillator to generate an error signal, which regulates the frequency of the digital data signals. The modulated signals are then sampled to corresponding analog values by a digital-to-analog converter, enhancing the efficiency of data transmission.
