Title: The Innovations of Richard E De Freitas
Introduction
Richard E De Freitas is an accomplished inventor based in Westford, MA, known for his significant contributions to the field of digital electronics. With a total of three patents to his name, De Freitas has consistently showcased his innovative approach to overcoming technological challenges.
Latest Patents
De Freitas' most recent patent focuses on digital encoding circuitry. This electrical system is designed to determine a digitally-encoded signal based on the difference between a present analog input signal and a reconstructed signal representing a past value of that input signal. Notably, the circuitry includes a mechanism for generating the reconstructed signal, which is responsive to a reference signal. The improved circuitry utilizes a ladder network to enhance the reference signal's magnitude, particularly as the digitally-encoded signal remains in a digital state for extended periods.
Another significant patent is for a multiple state responsive delta-sigma converter and delay line. This innovation features a digital delay line that efficiently converts between analog and digital signal formats. The system transforms an analog output into a series of binary signals, processed through a shift register at a designated clock rate. The conversion process is regulated by a logic network that enhances conversion efficiency, allowing for a lower clock rate and shorter shift register without sacrificing frequency response.
