Abstract
A frequency input for receiving a frequency signal and digital storing for storing the received frequency signal. A controller has a first and second input and an output. The first input is connected to the digital storage for providing a reference signal and the output provides a frequency control signal. The second input is connected to circuitry for changing the operation mode of the controller to either an amplifier or an integratory. As an amplifier, a digitally set offset and gain is applied to the amplifier for providing an output generating approximately the frequency of a prior signal. A switch connects the frequency output to the second input when operating in the integrating mode to control the output for generating a desired frequency.
