Abstract:

Efforts were continued on a feasibility study and investigation of interference reduction techniques applicable to nonlinear devices. The work is divided into two phases Phase I consists of the establishment of proper mathematical models that will be generally applicable to mixers and modulators in the 3-Mc to 100-Mc region, and Phase II consists of the use of these general mathematical models to find the optimum transfer characteristics for an idealized signal output. The nonlinearities that are determined from specifying a continuous band of harmonics were investigated. Representative characteristics for one-port and two-port devices were determined. Their behavior when subject to static changes in signal parameters was calculated. The problems of the sensitivity of the output to variations of input signals and the distortion that would be introduced by such a device were considered. Possible techniques to improve the device characteristics with respect to distortion and sensitivity are suggested. One such technique was investigated. Author
