PROBLEM TO BE SOLVED: To suppress a circuit scale.SOLUTION: An interpolation circuit includes: a generating circuit that generates interpolation data from a plurality of data of input data inputted in time series; a first ADC 40 that converts the interpolation data of a data point into digital data; and a second ADC 42 that converts the interpolation data of a change point into the digital data and has a quantization bit number smaller than that of the first ADC. |
