Title: The Innovative Contributions of Lauren A Christopher

Introduction

Lauren A Christopher is a notable inventor based in Indianapolis, IN (US). With a total of 5 patents to her name, she has made significant contributions to the field of technology and electronics. Her work primarily focuses on advanced signal processing techniques that enhance the quality and efficiency of digital communications.

Latest Patents

Among her latest patents is the "Fir filter apparatus for multiplexed processing of time division." This invention involves finite impulse response (FIR) filter circuitry designed for processing time division multiplexed sampled signals. The circuitry includes parallel sets of delay elements that delay respective signals to be filtered, with each set containing multiple taps. The corresponding taps of these delay elements are connected to a common weighting and summing structure, allowing for efficient signal processing.

Another significant patent is the "Multiple QAM digital television signal decoder." This invention utilizes a single adaptive passband equalizer to process a composite Quadrature Amplitude Modulated (QAM) signal. The equalizer output is phase corrected by a de-rotator and filtered to separate high priority (HP) and standard priority (SP) components. Error signals representing phase errors for both components are developed, which control the operation of the de-rotator and generate updated coefficients for the adaptive equalizer. Ultimately, the HP and SP components are decoded and combined for improved signal clarity.
