  • A charge sensitive amplifier for use with piezoelectric transducers

    Creator:
    Magnuson, Waldo George, Jr.
    Abstract:
    The design of a preamplifier for use with a piezoelectric transducer is generally approached from the point of view that an extremely high input impedance is required to obtain low frequency response. However, piezoelectric transducers are essentially charge generators and this fact may be utilized in designing preamplifiers to be...

  • Design of high-input impedance, wideband transistorized amplifiers

    Creator:
    Huaccho Salazar, Reynaldo
    Abstract:
    Conventional bi-polar transistors are inherently low input impedance devices. Transistor amplifiers have been designed which will present high input impedance, but the frequency response is limited to low frequencies, hundreds of kilocycles. This thesis investigates both field effect transistors and positive feedback as applied to high input impedance wide band...

  • Two-integrator detector for known-signal-in-noise identification

    Creator:
    Albright, Robert James
    Abstract:
    This thesis discusses the design and evaluation of an instrument that can detect known signals in noise. This detector uses two integrators to sense a difference in the received signal between half-cycles of the known signal. The detector is useful for sensing signals in the approximate frequency range of 100...

  • Medium frequency solid-state correlator

    Creator:
    Hill, Douglas Glenn
    Abstract:
    Periodic signals hidden in noise may be detected by using correlation techniques This thesis presents a study of how correlation is approximated statistically, and carried out electronically. The ability to detect periodic signals in noise, using correlation, is justified mathematically in the first portion of the thesis. The discussion is...
