Abstract
Disclosed are control systems, and more specifically control systems which benefit from a long-gate time for measurement and a rapid sample time to enhance responsiveness and methods and systems for utilizing multiple-staggered, overlapping gates where the gate time is an integer multiple of the time between ends of adjacent gates. The system continuously counts at the wavefronts or zero-crossings of a frequency reference signal and temporarily records them in registers and compares the contents of registers separated by a gate time and outputs a sample after every sample time.
