  • Method and apparatus for generating random numbers using electrical noise
    Patent number: 5627775
    Abstract: A random number generating apparatus includes a noise source, a circuit for generating timing signals from the noise source, and a digital circuit that freely and continuously cycles through a predetermined distribution of states. The states of the digital circuit are stored at random times in accordance with the timing signals and are collected to form bytes of random numbers.

  • Real time analysis of voiced sounds
    Patent number: 3978287
    Abstract: A power spectrum analysis of the harmonic content of a voiced sound signal is conducted in real time by phase-lock-loop tracking of the fundamental frequency, f.sub.o, of the signal and successive harmonics h.sub.l through h.sub.n of the fundamental frequency, measuring the quadrature power and phase of each frequency tracked, differentiating the power measurements of the harmonics in adjacent pairs and analyzing successive differentials to determine peak power points in the power spectrum for display or use in analysis of voiced sound, such as for voice recognition.
