Title: The Innovative Mind of Roubik Gregorian

Introduction

Roubik Gregorian, a distinguished inventor based in Saratoga, CA, has made significant contributions to the field of analog signal processing. With a remarkable portfolio of 18 patents, his work has enhanced various technologies, particularly in echo cancellation systems.

Latest Patents

Among his latest innovations is the patent for an "Analog Echo Canceller with Interpolating Output." This invention describes a method and system for canceling echo signals in the analog domain. The system includes an echo canceller featuring an interpolation unit that operates in the digital domain, effectively generating a second digital echo estimate signal without oversampling. A digital-to-analog converter (DAC) then transforms this signal into an analog echo estimate signal, thereby preventing unwanted high-frequency components. This sophisticated architecture culminates in a subtractor that effectively reduces the echo signal, leaving a clearer incoming signal.

Another notable patent by Gregorian is the "Analog Echo Canceller with Filter Banks." This innovation showcases a method for canceling echo signals using adaptive filters that operate in the digital domain. The system features an analog-to-digital converter (ADC) that samples at two different phases, generating distinct error signals for independent training of two adaptive filter units. The result is a meticulous cancellation of echo signals, contributing to clearer audio output.
