ABSTRACT:
The invention relates to an electric circuit for a telemetric transmission. A semiconductor transistor switch switches a quenching circuit into an electrically conductive state to prevent oscillation of a resonance circuit. The semiconductor transistor switch switches the quenching circuit into a state preventing the passage of electric current to enable oscillation of the resonance circuit. The quenching circuit comprises at least one restriction component for preventing the passage of a base current of the semiconductor transistor switch when the semiconductor transistor switch is switched open.
