ANALOG SIMULATION OF SAMPLED DATA SYSTEMS.

Abstract

Circuits have been devised in which relay controlled sampling followed by a zero order hold, a first order hold, or no hold may be simulated using available analog computer components and additional capacitors. The narrow sampling impulses are not explicitly generated and the switching rate is determined by the sampling period, providing for satisfactory relay operation. A variation of the state variable approach is presented, based on a partial fraction expansion of the system transfer functions. A method of separating analytically continuous data from sampled data in complex systems, thereby reducing calculations, is suggested. Difference equations for several elementary transfer functions are tabulated. (Author)
