摘要 |
<p>A signal processing circuit includes a delaying unit that is configured to carry out delay processing on the basis of periodicity information synchronized with the periodicity of a periodic noise included in an input signal and a filter unit that is configured to receive the input signal and has a notch characteristic at a frequency f. The frequency f satisfies f=N/T, where N represents an integer equal to or greater than one and T represents a delaying time applied by the delaying unit.</p> |
