ARTICLE Most documents available from AIAA Technical Library Journa1 Announcement: IAA8501 A method is proposed for the analysis of the frequency characteristics of linear systems with periodically varying parameters (e.g., parametric amplifiers, frequency converters,.electromechanical devices with magnetic bearings, etc.). The method is based on the expansion of the solution of the appropriate differential equation in a power series of the auxiliary parameter. Recursive relationships are obtained for determining the amplitude-phase frequency characteristics. (B. 0 .)

ARTICLE Most documents available from AIAA Technical Library J our n al An n ouncement: IAA8501 Attention is given to the circuit of a sensor of nonelectrical quantities synthesized on the basis of series functional converters. Formulas are presented for calculating the main errors of the transducer, and an experimental validation of the results is carried out on the example of the linearization of the power characteristics of photoresistors. Given a significant nonlinearity of the sensors used, the nonlinearity of the conversion characteristic does not exceed 1 percent. (B.J.)
