Abstract
Disclosed is a phase measurement system and method. Multiple frequency orthogonal signals are transmitted simultaneously along the same row conductor. One of the signals may be low frequency signal. The other signal may be a high frequency signal. The field of the low frequency signal may extend further above a touch surface than the high frequency signal. The phase data from the low frequency signal may be used to provide information about a touch event.
