Abstract: An apparatus for detecting the wobble carrier frequency of an optical disk is disclosed. The apparatus comprises an offset canceller, a binary conversion module, an adjustable band pass filter, and a frequency detection module. The offset canceller cancels the direct current offset of a first wobble signal to obtain a second wobble signal. The binary conversion module converts the second wobble signal to a binary data stream. The adjustable band pass filter passes only an adjustable frequency range of the binary data stream to generate a filtered signal, wherein the center frequency of the adjustable frequency range is sequentially adjusted. The frequency detection module then determines maximum amplitude of the filtered signal, and determines the center frequency of the adjustable frequency range according to which the filtered signal with the maximum amplitude is generated, wherein the wobble carrier frequency is the center frequency corresponding to the maximum amplitude.

Abstract: The invention provides a wobble detection circuit. An exemplary embodiment of the wobble detection circuit comprises an automatic gain control module, an analog to digital converter, a digital band pass filter, and a digital band pass filter. The automatic gain control module amplifies a first input signal and a second input signal detected by a pickup head to the same magnitude to obtain a first amplified signal and a second amplified signal. The adder then subtracts the second amplified signal from the first amplified signal to obtain an analog wobble signal. The analog to digital converter then converts the analog wobble signal to a first digital wobble signal. Finally, the digital band pass filter accepts frequency components of the first digital wobble signal within a pass band and rejects frequency components of the first digital wobble signal outside the pass band to obtain a second digital wobble signal.
