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.
