Systems and methods for providing delayed signals |
摘要 |
A variable delay apparatus comprises a calibrating unit receiving a signal from a variable delay unit and from a plurality of fixed delay sources, the calibrating unit comparing the signal from the variable delay unit with a plurality of signals from the fixed delay sources to control operation of the variable delay unit over a delay range independently of environmentally-induced drift.
