DEFINITION

Classification: 331/112

(under subclass 111) Oscillators comprising at least one active element of the transistor type, a closely-coupled

transformer coupling the output circuit of the transistor to the input circuit in positive feedback relation and a time constant network in the input circuit of the transistor, the conduction and relaxation periods of the oscillator being determined by the impedance parameters of the transformer and time constant network.
