Abstract : The general method of amplification by periodically quenching an unstable system under the influence of an input signal is investigated by the use of mathematical calculation, digital computation and experimental verification. This type of amplification, of which superrgeneration is just one specialized form, is specifically analyzed for electrical systems which can be made unstable with time invarient elements. Specific results from the investigation of a system described by a first order differential equation reveals the physical realizability of an amplificatory mode of operation having unusual selectivity responses. The experimental realizability of this system was accomplished by the development of a special form of dynatron using characteristics heretofore not exploited. Specific results from the investigation of the system described by a second order differential equation revealed fundamental selectivity/gain limitations for the linear system, a limitation which can be overcome by the use of a time varying regenerative cycle. Both systems demonstrated the capability of having a very high voltage and power gain throughout the audio and radio frequency spectrum. (Author)
