Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin Jan 1976

Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin

Retrospective Theses and Dissertations

In this paper, two methods for the design of active analog feedback bandpass filter pairs are examined. A third method is presented that does not use extra amplifiers for summation nor multicoupling. This third method uses identical bandpass amplifies and employs resistor summing to provide multicoupling. The name of this configuration is the "Dual Amplifier Bandpass Filter Employing Resistor Summing" (DABFERS). This configuration is economically attractive, has low sensitivity and better phase lag characteristics. In addition, third order prototypes are examined and a solution method for higher order prototypes is suggested.


Dynamic And Stability Characteristics Of An Articulated Frame Railway Passenger Truck, David Kenneth Platner Jan 1976

Dynamic And Stability Characteristics Of An Articulated Frame Railway Passenger Truck, David Kenneth Platner

Retrospective Theses and Dissertations

Mass transit vehicles in formal rail service frequently attain speeds which can excited carbody oscillations (primary hunting), as well as sustained lateral oscillations of the trucks (secondary hunting). The carbody motions have been shown to generate passenger discomfort and sustained truck hunting can lead to derailment. This thesis developed approximate equations which predict the carbody hunting frequencies, as well as the hunting speed of an articulated frame truck. The linear equations of motion are derived from a simplified model of a railway vehicle. A comparison indicates the results obtained using the approximate truck hunting equation presented here are within ten …


The Effects Of Altered Traffic Signs Upon Vehicular Driving Modes And Consequent Fuel Conservation And Environmental Benefits, As Measured By Vehicular Noise-Imprints, Mark Daniel Pfarrer Jan 1976

The Effects Of Altered Traffic Signs Upon Vehicular Driving Modes And Consequent Fuel Conservation And Environmental Benefits, As Measured By Vehicular Noise-Imprints, Mark Daniel Pfarrer

Retrospective Theses and Dissertations

The hypothesis is that the recorded noise-imprints of a vehicle at an intersection can be used to identify and accurately time the driving modes of deceleration, idle, slow cruise, and acceleration. This is proven by analyzing and comparing noise-imprints of vehicles at an uncontrolled intersection marked first with a "stop" sign, and then by a "yield" and an experimental "dead slow" sign. By relating the duration of each driving mode to known relations, the overall efficiency of an intersection can be characterized. A new technique for studying various types of traffic conditions at intersections is the result. Initial noise-imprint analysis …
