Signal Processing Expert Witnesses

The developing new technology of digital signal processing is the focus of many of the expert witnesses at ForensisGroup. Digital signal processing is the representation of a signal by a sequence of numbers, which can be altered via a computing process to change or extract information from the original signal. They have also been involved with the research and development of wireless and wired transceiver systems and architectures, wireless transmission, data transmission, technology development, smart antennas for wireless communications, advanced signaling and interference mitigation techniques, and other digital transmission systems.

Many of our signal processing expert witnesses have years of experience in electrical engineering and specialize in signal processing, detection, computer simulations, and multi-beam antennas. Digital signal processing is found in digital audio, digital music, speech processing, voice processing, consumer audio devices, and includes the development of audio-related algorithms, software and products, machine learning, sound perception, and noise reduction.

Signal processing expert witnesses from ForensisGroup have assisted law firms with litigation concerning motion picture patent claims, and audio and video piracy of theatrical release motion pictures. Signal Processing Experts have served as college faculty teaching courses on Sound Reinforcement and Recording, Electrical Engineers, executives in charge of Licensing Engineering, and Signal Processing Project Engineers.
