Introduction

Thomas E. Clark is a notable inventor based in San Mateo, California. He is recognized for his contributions to the field of digital signal processing, particularly through his innovative patent for a digital phase detector. His work has implications in various applications where phase modulation is essential.

Latest Patents

Thomas E. Clark holds a patent for a digital phase detector. This invention periodically detects the phase angle θ_k of a carrier signal in which data are encoded as discrete phase changes. The coherent or differential phase-modulated carrier signal is split into its in-phase and quadrature phase components, R_o Sin(θ(t)) and R_o Cos(θ(t)). Each signal component is sampled at a predetermined modulation interval and converted into a digital word. The digital words are then processed to extract the encoded data, which is proportional to the phase angle θ_k.
