Title: The Innovations of Robert Fifield
Introduction
Robert Fifield is a notable inventor based in Redhill, GB, recognized for his contributions to the field of radio technology. With a total of 11 patents to his name, he has made significant advancements that enhance the functionality and efficiency of radio receivers and digital signal processing.
Latest Patents
Among his latest patents is a radio receiver gain control system. This innovative design includes an analogue to digital converter that generates a data word representative of a received radio signal. The gain control stage is equipped with a first register for storing the data word, allowing for precise control over the numerical value of the data word by adjusting its position within the register. Another significant patent involves fractional frequency and sampling-rate change in the frequency domain. This arrangement and method digitally filter a time-discrete digital signal by transforming it to the frequency domain using discrete Fourier transformation. The signal is then filtered in the frequency domain, with the filter response adaptable in real time to changes in the interference environment. Finally, the filtered signal is transformed back to the time domain using inverse discrete Fourier transformation, creating an output signal with adjusted bin frequencies and sampling rates.
