Apparatus and Method for Reducing Jitter in Periodic Signals |
| 摘要 |
The present invention provides an apparatus and method for reducing jitter in a periodic signal. The apparatus comprises: a frequency discriminator configured to receive the periodic signal and feedback of an output signal of the apparatus and calculate an estimate value for a length of a current period of the periodic signal; a phase discriminator configured to receive the periodic signal and determine an adjustment factor for the length of the current period of an input signal according to the input signal in a previous period of the periodic signal and the output signal in the previous period of the apparatus; and an adjustor configured to determine the period length of the output signal in the current period according to the estimate value for the length of the current period and the adjustment factor for the length of the current period. |
