Title: Brian John Minnis: Innovator in Digital Signal Processing
Introduction
Brian John Minnis is a notable inventor based in Crawley, GB. He has made significant contributions to the field of digital signal processing, holding a total of 16 patents. His work focuses on innovative methods and arrangements that enhance the performance of digital systems.
Latest Patents
Among his latest patents is a method for fractional frequency and sampling-rate change in the frequency domain. This invention involves digitally filtering 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, allowing for real-time adaptation of the filter response to changes in the interference environment. The filtered signal is subsequently transformed back to the time domain using inverse discrete Fourier transformation to create an output signal. Additionally, he has developed an RF transmitter with compensation of differential path delay. This transmitter features a power amplifier that amplifies an input signal with amplitude modulation, along with a supply voltage controller that adjusts the power amplifier's supply voltage according to the envelope. The design includes a sensor for monitoring the modulation of the current drawn by the power amplifier, a delay detector for identifying the delay of the controlled supply voltage, and a delay adjuster for compensating the relative delay. This innovative approach effectively reduces distortion and out-of-band emissions caused by differential delays.
