ABSTRACT:
A method and apparatus for obtaining high frequency resolution of a low frequency data signal are provided. The invention comprises a low frequency select logic 27 for generating the data signal having low frequency resolution, low frequency state machine logic 29 for determining whether the data signal is resolved to predetermined high frequency resolution characteristics and circuitry for generating a correction signal to modify the data signal to high frequency resolution, and high frequency logic 17 for modifying the data signal in response to the low frequency correction signal. The high frequency logic 17 operates to selectively modify the path of low frequency data in response to the correction signal to modify the low frequency data signal to obtain high frequency resolution.
