AN ANALOG TRIODE-DIODE FUNCTION GENERATOR,
Abstract
A triode-diode function generator, for use with a general purpose analog computer, is designed and evaluated. The characteristics of an operational amplifier, a diode switch, and a triode switch are investigated. The use of these components in gain switching function generators is illustrated by descriptions of the operation and adjustment of a diode function generator, a triode function generator, and a triode-diode function generator. The detailed design of a practical triode-diode function generator is carried out stage by stage, and the transfer function for each stage is obtained. Stability of the function generator is studied both in terms of it being a linear system and a simple nonlinear system. The triode-diode function generator is evaluated analytically and by testing a prototype. Characteristics are obtained from test and documented for comparison with design specifications. Test procedures are described and evaluated. A quantitative comparison of errors, due to drift, noise and bandwidth, is made between the diode function generator and the triodediode function generator for a particular case. (Author)
