Abstract
A device for reducing turn-off time of a transient electromagnetic transmitting signal includes a transmitting coil, a first electronic switch to control connection mode of the transmitting coil and a second electronic switch configured to form a bridge arm. The transmitting coil is a twisted pair including a first wire and a second wire. The first wire is connected to one end of the second electronic switch. The other end of the second electronic switch is connected to one end of the first electronic switch. The other end of the first electronic switch is connected to the second wire. The connection mode of the transmitting coil includes head-to-head connection, head-to-tail connection and tail-to-tail connection between the first wire and the second wire. The first wire and the second wire are connected to form a transmitting loop.
