Abstract
A method includes receiving by wireless transmission, a first signal transmitted by a digitizer system. The first signal is configured to define a detection period during which a second signal may be detected by the digitizer system. The method further includes detecting timing of the receiving, detecting a first delay in the receiving due to amplification associated with the receiving, defining timing to transmit the second signal based on the timing of the receiving and the first delay and transmitting the second signal at the timing defined. The second signal is transmitted with a handheld device by wireless transmission and the first delay is detected by the handheld device that is receiving the first signal and transmitting the second signal.
