Abstract
An interpolation circuit capable of performing interpolation operation with a simple constitution. A 16-times oversampling from discrete data is performed by D frip-frops. A first convolution operation is performed by D frip-fropsthroughand an adder, on the result of which a second convolution operation is performed by D frip-fropsthroughand an adder. Data interpolated along a quadratic function curve interpolating the discrete data is obtained from the adder
