Title: Innovations of Thomas M. Stiller
Introduction
Thomas M. Stiller is a notable inventor based in Ewing Township, NJ, who has made significant contributions to the field of digital signal processing. With a total of two patents to his name, Stiller's work focuses on enhancing the efficiency and effectiveness of digital systems.
Latest Patents
Stiller's latest patents include a digital signal processing system employing logarithms to multiply and divide. This innovative system applies numbers to the multiplied or divided values to address a memory storing a logarithm table, producing the logarithms of the numbers. The logarithms are then added for multiplication or subtracted for division, resulting in the logarithm of the outcome, which is used to access a memory storing an antilogarithm table to produce the final result. The base of the logarithms is selected based on the magnitudes of the numbers involved, ensuring the entire range of magnitudes of the digital representation of the logarithms is utilized.
Another significant patent is the logarithmic color matrix for a digital television receiver. In this system, a signal processing stage generates color mixture digital signals that represent color picture information as components in a first color mixture coordinate system, such as the I-Q system. The I and Q digital signals are processed through a read-only memory look-up table, which contains the logarithmic values of the signals, converting them into digital words represented in logarithmic form. A microprocessor generates or retrieves digital coefficients in logarithmic form, enabling the transformation of the I and Q digital signals into second color mixture digital signals representing color picture information in a different coordinate system.
