  • 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...

  • The design and performance of a wideband electronic correlator

    Creator:
    Spencer, Gary Edward
    Abstract:
    In communications it is often desirable to recover a signal hidden in noise. The techniques of correlation are often employed for this purpose. Initially, the basic formula and properties of correlation including an approximating formula are presented. Then the description, design, and construction of a DC to 500 KHz electronic...

  • Digital filtering with an IBM 1620 computer

    Creator:
    Smathers, Douglas Charles
    Abstract:
    Digital filtering can be done on a limited scale using an IBM 1620 digital computer. A computer program has been written to aid in the design of digital filters by computing the power spectrum of sampled time data. The power spectrum analysis program was coded in SPS symbolic machine language....

  • The design and evaluation of an electronic estimator of probability density distributions

    Creator:
    Senk, Frederick Martin
    Abstract:
    This thesis discusses the design and evaluation of an instrument that can estimate the probability density distributions of bandlimited, aperiodic electrical phenomena. This estimator can obtain the probability density estimates of signals that are contained within the frequency range of 100 cps. to 20 kcs. However, the basic design logic...

  • A vector electrocardioscope system for clinical studies

    Creator:
    Petersen, Walter Anton
    Abstract:
    This paper discussed the human electrocardiogram, the instrumentation used to graphically record it, and the design and performance of a specialized system for vector cardiography: the Vector Electrocardioscope (VECS) System. The introduction reviews in considerable detail the pertinent known physiology of the heart, especially the electrophysiology responsible for the genesis...

  • 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...

  • Short-pulsed operation of the balanced detector

    Creator:
    Williamson, James Allen
    Abstract:
    The problem that is attacked in this paper is that of analyzing and predicting the response of a balanced detector when it is driven by short, periodic bursts of RF energy. There is, however, sufficient information provided to extend the analysis to virtually any circumstance of balanced detector operation. The...

  • A zero-crossing analyzer for distribution-free detection of a signal in noise

    Creator:
    Bertorello, Robert James
    Abstract:
    This thesis discusses the analysis, design, and experimental evaluation of an instrument that can be used to detect the presence or absence of a signal, not necessarily known, in a noisy background. The detection principle is based on application of the sign test of distribution-free statistics to the stochastic process...

  • An approximate matched filter design for detecting a pulsed carrier in noise

    Creator:
    Wang, Chʻeng-chi
    Abstract:
    This thesis discusses the design of an approximate matched filter capable of detecting a 30 MHz, 0.45 microsecond pulsed carrier in white noise. The theoretical background, which the matched filter is based upon, is presented. The matched filter described herein is composed of an open-end lumped-parameter delay line and a...

  • 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...
