Abstract
A delay amount estimating apparatus includes a delay value search section that searches for a first delay value smaller than a delay setting value at which a given correlation value between an input signal and a feedback signal is provided, and also for a second delay value greater than the delay setting value, the feedback signal coming from a signal processing apparatus that applies signal processing on the input signal, wherein respective correlation values of the first delay value and the second delay value satisfy a given condition; and a delay estimating section that estimates a delay amount of the feedback signal relative to the input signal based on the first delay value and the second delay value.
