Claims

[Scope of utility model registration request]

In a single-core magnetic multivibrator mainly composed of two switching transistors connected symmetrically with a common emitter and a saturable transformer, the bases and base windings of each of the two switching transistors , connect diodes in series with their cathodes on the base side, and connect diodes repeatedly from the outside between either one of the connection points and the power input terminal connected in series with the common emitter. A magnetic multivibrator-0 characterized in that the self-oscillation frequency can be controlled by applying a pulse signal.
