Title: Innovations by William M. Hubbard in Digital Circuitry

Introduction

William M. Hubbard is a notable inventor based in Colts Neck, NJ, who has made significant contributions to digital circuit technology. With a total of five patents to his name, his work primarily focuses on the advancement of demultiplexer circuits, which are crucial for modern communication systems.

Latest Patents

Among his latest innovations are two distinct patents for demultiplexer circuits. The first patent describes a demultiplexer circuit capable of extracting any combination of PCM encoded words or data bits from an incoming time division multiplexed digital bit stream. This invention utilizes a random access memory (RAM) to store data indicating which bits to demultiplex. A counter synchronizes with the received bit stream, accessing the RAM to provide output signals that identify the relevant bits for subscriber stations. Additionally, this circuit enables summation of conference calls in real-time, with digital signals being read into separate random access memories for steady output without concern for signal rate variations.

The second patent covers a similar design, emphasizing the capabilities of a shift register to read digital signals intended for subscriber stations. It highlights real-time summation of conference calls and efficient transfer of data between registers. This collection of patents reflects Hubbard's commitment to enhancing digital communication.
