Abstract:
1. An interpolation circuit comprising: a first circuit that generates first interpolation data from a plurality of pieces of data among data inputted in time series; a second circuit that generates second interpolation data from the plurality of pieces of data in timing when a part of the data inputted in time series in the first circuit lacks; and a third circuit that adds the second interpolation data to a location in the first interpolation data where the part of the data inputted in time series has lacked, a control circuit that changes an interpolation coefficient to be supplied to the first circuit for each given period, wherein the first circuit generates the first interpolation data using the interpolation coefficient, the second circuit generates the second interpolation data using an interpolation coefficient different from the interpolation coefficient of the first circuit, and the part of the data lacks in timing is when the interpolation coefficient is changed.
