Abstract
A semiconductor device contains a narrow band noise detector section to detect narrow band noise in an input signal that is input by way of a power line. The semiconductor device further includes a reference signal generator section to generate a second reference signal whose amplitude value which corresponds to the narrow band noise frequency of a pre-established first reference signal is reduced, and a correlation calculation section to calculate the correlation value between the input signal and the second reference signal utilized in the frame synchronization processing of the input signal.
