Document Type and Number:
Japanese Patent JP4519818
Kind Code:
B2
Abstract:
A method of suppressing leakage electromagnetic fields on a communication line or a power line having reflected waves includes the steps of (a) transmitting a first impulse from a transmission end and (b) transmitting a second impulse from the transmission end after passage of a given period of time during which a reflected wave of the first impulse disappears before returning to the transmission end. Thereby, the leakage electromagnetic fields are minimized.
