摘要: Methods and apparatuses consistent with the present invention recover a clock signal (160) from variable bit rate data by estimating, in time domain, of signal, based on estimated rate, determining center frequency narrow-band filter (330) for extracting (155). A recovery circuit (300) extracts estimating minimum interval between transition (320) generating plurality pulses that correspond respectively to transitions adjusting duration each (310) inputting into adjusted (RS2), interval, pulses.
