<p>The equipment uses primary and secondary inductors (34,36) which connected in series with a capacitor (40). The circuit is connected to a battery (38) and the common point of the inductors is connected to earth through a transistor (30,31) receiving square wave control signals. During successive periods of transistor conduction and blockage the inductors transmit in forced and free oscillation mode</p> |
