    Company description: Quantum Signal LLC is an engineering services company located in Ann Arbor, Michigan specializing in advanced signal processing and pragmatic algorithmic solutions. Signal processing may be defined as the extraction of useful information from noisy, corrupt, or otherwise difficult to process data. It has evolved from algorithms and tools useful in electrical engineering, mechanical engineering, statistics, physics, and mathematics. The goal is to answer questions about the state of a system based on measured signals.
    As a leader in this dynamic field, the Ann Arbor-based firm is developing state-of-the-art algorithmic solutions for a variety of applications and clients. Quantum Signal was co-founded by Professor William J. Williams of the University of Michigan and two former graduate students, Dr. Mitchell Rohde and Dr. Eugene Zalubas. Quantum Signal is transitioning exciting signal processing concepts and technologies out of the ivory tower and into a wide variety of commercial applications. Quantum Signal works with clients in a plethora of industries, including automotive, defense and intelligence, power generation, and aerospace.
    Quantum Signal has extensive experience in multidimensional, non-linear, and transient signal processing. Some of the more common techniques that we work with include Fourier analysis, modern spectral analysis, wavelets, neural networks, statistical methods, scale transforms, non-linear algorithms, image processing, adaptive filtering, fuzzy logic, and principal components (PCA). Quantum Signal specializes in modern Time Frequency Analysis, a field in which Dr. Williams has made major contributions. Some of the Time-Frequency kernels that we work with include the Wigner, Binomial, Exponential, and Reduced Interference Distribution (RID).
    Quantum Signal is a small business that can provide services such as custom algorithm development, estimation and detection, data analysis, characterization, and mining, sensor analysis, algorithm performance measurement, pattern recognition, prognostics/diagnostics, and feature extraction/classification. The company currently is developing an advanced algorithm useful for word spotting, biometric recognition, and other pattern recognition tasks.
    Founded in 1999, Quantum Signal is a profitable, growing small business with a staff of seven. It is privately owned and funded.
