Title: The Innovations of Timothy H Pearce
Introduction
Timothy H Pearce is a notable inventor based in Chelmsford, GB. He has made significant contributions to the field of electronics, particularly in the development of analogue-to-digital and digital-to-analogue converters. With a total of 4 patents to his name, Pearce's work has had a lasting impact on the industry.
Latest Patents
Among his latest patents, Pearce has developed an innovative analogue-to-digital converter that includes a filter designed to receive a signal derived from the analog input signal. This converter features a first quantizer that produces a digital signal from the filter's output. A feedback loop is incorporated to combine the first digital signal with the analog input signal, allowing the filter to receive an error signal that represents the difference between the two. Additionally, an error signal filter is utilized to eliminate noise outside the passband of the converter. Pearce's second quantizer then generates a second digital signal that represents the filtered error signal, ultimately combining both digital signals to produce a digital output representative of the analog input signal.
Another significant patent involves a radar receiver that processes FMCW radar return signals. In this design, the signals are converted to intermediate frequency in a front-end section and digitized in an A-D converter. The system reduces the signals to in-phase and quadrature baseband components at a lower sampling rate. By comparing returns with a separate reference waveform signal for each range cell, Pearce's design allows for the use of non-linear sweep waveforms, enhancing the radar's operational capabilities.
