Introduction

Andrew Martin Roberts is a notable inventor based in Leeds, GB. He has made significant contributions to the field of signal processing, holding a total of 2 patents. His work focuses on developing innovative solutions for analog and digital signal conversion.

Latest Patents

Roberts' latest patents include a demodulator for a pulse width modulated (PWM) signal and an analog to digital converter utilizing an up/down counter and digital feedback. The demodulator is designed to count in both directions based on the PWM signal's state, allowing for an accurate representation of the duty cycle. This innovation enables the determination of the duty ratio of the PWM signal, independent of its frequency. The analog to digital converter incorporates a comparator and an up/down counter, where the counter's output reflects the converted digital word. This word is then used to adjust the modulation duty cycle, ensuring precise digital output that corresponds to the analog input.
