Title: Alfred Edward Parker: Innovator in Amplitude Modulation Technology

Introduction

Alfred Edward Parker is a notable inventor based in Hicksville, NY (US). He has made significant contributions to the field of amplitude modulation, particularly in commercial broadcasting. His innovative approach has led to advancements that push the boundaries of conventional modulation techniques.

Latest Patents

Parker holds a patent for "Amplitude modulation with time- and spectrum-shared sidebands." This patent describes a system that generates and processes a pure unmodulated carrier signal and two sideband signals as three independent signals. These signals are summed as the output of a final linear mixer. The sideband signals are derived independently through audio spectrum-sharing, utilizing complementary comb filtering and quadrature phase-shifting. This method allows for exclusive alternate toggling between the two sidebands, ensuring that at any given moment, only one sideband is present alongside the continuous carrier. This innovative approach enhances modulation capabilities beyond the conventional 100% modulation limit.
