Title: Innovations of Charles Robert Hewes
Introduction
Charles Robert Hewes is a notable inventor based in Dallas, TX, with a remarkable portfolio of six patents. His contributions to technology, particularly in the field of telecommunications and signal processing, have made a significant impact on modern devices.
Latest Patents
Hewes' latest patents include innovative designs such as charge coupled device filters and modems incorporating such filters. One of his notable inventions is a modem utilizing process technology compatible with CCD and IGFET circuits and subsystems incorporated on a single integrated circuit chip. This modem employs CCD transversal filters as bandpass filters, which can be tuned for different modes of operation by adjusting the clock frequency. The bandpass filters work in conjunction with a charge amplifier to eliminate d.c. offset from the analog output. Additionally, the demodulator section of the modem features a low-pass filter that utilizes switched resistors. The modulator section includes waveform generators based on a digital-to-analog converter, which generates a sine wave with minimal distortion when switched in the proper sequence. The modem can also be operated under the control of a microprocessor. Another significant invention is the charge-transfer programmable filter, which is a one-bit by N correlation digitally programmable filter. This filter comprises a multi-phase charge-transfer shift register, with phases selectively clocked to achieve programming. One phase is connected to an integrator circuit that generates an output voltage proportional to the sum of the charged packets transferred.
