ABSTRACT:
A clock generating apparatus for use in an electronic device, such as a radio or other audio device, which generates a clock signal based on an AC input signal received, for example, from a wall outlet. The clock generating apparatus detects and monitors the frequency of the AC input signal and automatically adjusts the clock signal based on the detected frequency of the AC input signal.
