Abstract
In a feedforward control type reproduced signal processor, a clock generatorchanges a clock frequency, depending on a digital value set by a digital value generator. Therefore, power consumption of a system is optimized and control is facilitated. Moreover, when a frequency lock state is established in which a frequency ratio calculated by a frequency ratio calculatorsatisfies a set condition, a modulation component having a small change is generated using a clock of a clock generator. Therefore, the digital value is updated with the modulation component, so that a change in clock frequency of the clock generatorgradually varies. As a result, the influence of the change in clock frequency on the response of a decoding process is reduced.
