Title: Innovations of Wade J. Stone
Introduction
Wade J. Stone is a notable inventor based in Los Angeles, California. He has made significant contributions to the field of analog-to-digital conversion and digital signal processing. With a total of six patents to his name, his work has had a profound impact on technology.
Latest Patents
One of his latest patents is the "Feed forward predictive analog-to-digital converter." This invention employs a fully feed forward design to extend dynamic range, enhance speed of operation, and eliminate the need for sample-and-hold circuits. The first quantizer converts an input analog signal to a digital format, while a signal predictor anticipates the subsequent value of the input signal. After conversion back to analog, the predicted signal is compared with the actual value to produce an error signal, which is then converted to digital format by a second quantizer. This process results in a high precision digital output.
Another significant patent is the "Efficient digital frequency division multiplexed signal receiver." This invention is designed for digital radio frequency or intermediate frequency receivers that handle frequency division multiplexed signals. It includes an RF amplifier, an RF bandpass anti-alias filter, and an analog-to-digital converter. The A/D converter operates at a sample frequency lower than the lowest frequency in the predetermined FDM band, ensuring that the output contains a non-distorted aliased frequency down-converted digital version of the FDM band.
