Title: The Innovations of John R. Linford
Introduction
John R. Linford is a notable inventor based in Broomfield, Colorado. He has made significant contributions to the field of digital signal processing, holding a total of 3 patents. His work primarily focuses on developing innovative techniques for filtering and processing analog signals.
Latest Patents
One of Linford's latest patents is a low pass digital averaging filter. This invention discloses a circuit designed to extract a low-frequency signal component from a composite signal using a digital averaging technique. The circuit employs an analog to digital converter that receives a composite analog signal and provides a digital output signal. The digital output is sampled during periodic intervals, and the adder/subtractor circuit processes these signals to produce a running average. This method effectively filters out higher frequency components, enhancing the clarity of the desired low-frequency signals.
Another significant patent by Linford involves digital apparatus that approximates the multiplication of an analog signal by a sine wave. This method utilizes digital techniques to convert an analog signal into a digital representation, which includes a binary sign bit and multiple binary magnitude bits. The sign bit is selectively complemented by an inverting logic gate, controlled by a square wave signal. This innovative approach allows for the effective detection and processing of the analog signal through quasi-digital multiplication.
