On extending audio feedback loops to include electrodynamic speakers
Summary. The purpose of the investigation was to determine the applicability of extending inverse feedback techniques to electrodynamic loudspeakers by finding first, what the general limitations were, and second, how much ...
A servomechanism pantagraph
A low frequency oscillator
An investigation of certain problems in the use of sample cores in analog simulation of magnetic amplifier circuits
In order to establish the conversion factors between an actual circuit and its computer simulation, the simple half wave magnetic amplifier-circuit was used. The Computer simulation of this circuit requires three operational ...
An investigation of a criterion for the optimum transient response of servo-mechanisms
A new criterion for the optimum transient response or linear systems (in particular regulating systems) is discussed and investigated. The criterion is evaluated analytically for systems of the second and third order. ...
An application of analog computer techniques to the problem of interpretation of the contact log
It is hoped that the following report may serve as the groundwork or basis for further applications of analog computer techniques to the field of electrical well logging interpretation. The author feels that this type of ...
An investigation of a condenser microphone as a pressure transducer
The device described is a preasure-sensitive transducer. commercially available condenser microphone, a Stephens model C-1 was used as a capacitor manometer. The instrument was developed for use in breath velocity studies ...
