11	A special purpose analog computer for statistical system identification Fieguth, Werner January 1965 (has links) An iterative method of system identification based on solving the integral equation [Formula omitted] for h(σ) at ten equally spaced points (σ[subscript i] = 1,2,..,10) is described. Replacing the above integral by a finite sum at ten different values of τ results in a set of ten equations in the ten unknowns h(σ[subscript i]). A statistically identical and much more easily handled set of equations, obtained by using one-sample products in place of the actual correlation functions, is then solved by a Gauss-Seidel-like iteration method, the convergence properties of which show this approach to the identification problem to be a useful one for a large class of system input signals. A simple computer to realize the above identification method is described in some detail. The use of a simple quantization form of correlation allows shift registers to carry out the required delay operations. Storage for the computer's estimates of the h(σ[subscript i]) is in the form of step motor driven potentiometers, which also carry out one of the multiplication operations. The very encouraging results of a number of relatively realistic identification tests using the computer are given. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
12	A Differential Sample and Hold Technique that Rejects Offset Voltages Davis, John Adams 01 January 1976 (has links) (PDF) This research report discussed modern sample and hold theory and techniques and then uses them to develop a new differential sampling concept to solve a real engineering problem, involving the synchronous demodulation of three amplitude modulated direction cosine signals in an unusual noise environment. The problem is discussed in detail and a detailed circuit design solution given. Additionally, the results of a breadboard test of the concept is given that shows the circuit to have a 60dB offset voltage rejection ratio. Electronic analog computers Circuits Engineering
