Latency time determination system for a transceiver

摘要

A system to determine the length of time, known as the latency time, that is required to wait between transmitting and receiving data for a half-duplex electromagnetic transceiver having a transmitter and receiver wherein the receiver is electromagnetically coupled to the transmitter. The determination of the latency time is accomplished by the use of a control circuit that operates to turn the transmitter to an on state. The control circuit then monitors the receiver to determine when the receiver also goes to an on state due to the electromagnetic coupling. The control circuit subsequently turns off the transmitter and the length of time for the receiver to recover to an off state is measured. This length of time is the latency time and is used in subsequent transmission of data.
