Title: Innovations of Roy W. Gustafson
Introduction
Roy W. Gustafson is a notable inventor based in Boxborough, MA (US). He has made significant contributions to the field of communication technology, holding a total of 3 patents. His work focuses on methods and systems that enhance signal transmission and processing.
Latest Patents
One of Gustafson's latest patents is a method and apparatus for equalization for transmission over a band-limited communication channel. This technique compensates for frequency distortion by utilizing a random-access memory (RAM) to store successive samples of a signal pulse. The samples are precalculated to perform an equalization function prior to transmission. The signal samples are then retrieved, converted to analog form, and filtered to produce a precompensated analog pulse signal. In one embodiment, equalized profiles of various pulse shapes are stored in the RAM and retrieved as needed for transmission, allowing for effective encoding of the signal into different forms, such as modified duobinary code.
Another significant patent is an automatic gain control (AGC) system designed for amplifiers. This AGC system includes an AGC multiplexer and an AGC circuit. The AGC circuit generates a gain control signal in response to an input signal from the AGC multiplexer. The multiplexer operates in three modes, enabling it to detect erased portions of a sector, generate gain signals related to the output level of the amplifier, and maintain a constant output signal for consistent gain control.
