Title: Innovations of Samuel Joseph Campanella

Introduction

Samuel Joseph Campanella is a notable inventor based in Gaithersburg, MD (US). He holds three patents that showcase his contributions to the field of technology, particularly in signal processing and telecommunications. His innovative work has significantly impacted the efficiency of communication systems.

Latest Patents

One of Campanella's latest patents is the "Variable slope delta coding processor using adaptive prediction." This invention allows a digitized signal to be transmitted using approximately half the channel bandwidth required by previous techniques, without sacrificing signal quality. The process involves subtracting an estimate of a digital sample from an input signal to produce an error signal, which is then transmitted as a single bit output. The method utilizes a compression technique to calculate an adaptive step value, leading to the construction of reconstructed signal values for each input signal sample.

Another significant patent is the "Echo suppressor using frequency-selective center clipping." This invention is designed for the send path of long-distance telephone circuits. It employs frequency-selective center clipping to manage echo in communication channels. The bandwidth is divided into subchannels, and each signal is processed to predict threshold control voltages based on average speech amplitude distribution. This technique ensures that the center clipper thresholds are proportional to the average energies of telephone speech in respective frequency bands.
