Abstract
A method and system for digital resolution translation. An input frequency is received, as is a desired output frequency. The desired output frequency is measured directly and compared with the input frequency. The specified output frequency is dynamically adjusted to compensate for variations in the input frequency, while a fixed relationship between the input and output is kept intact. The relationship between the input and output frequencies can be arbitrary, non-integer or integer. The system consists of an execution process (54) and the adjusted output frequency is sent to a system as a sampling signal. The system reset/restart capability allows for a repeatable phase relationship between the output and the input from any given reset point.
