Abstract
Constantly increasing demand for synchronizing devices in telecommunication techniques has involved extended use of devices for the production of harmonics and subharmonics of an input master frequency. This article describes a new circuit for a generator by means of which frequency multiplication and division can be obtained The principle of feedback is applied in a new way to a valve circuit having a nonlinear response characteristic. The conditions for optimum output power are deduced and the advantages of the new circuit are discussed.
