<p>An interpolation circuit capable of performing interpolation operation with a simple constitution. A 16-times oversampling from discrete data is performed by D flip-flops (4, 5). A first convolution operation is performed by D flip-flops (4-11) and an adder (12), on the result of which a second convolution operation is performed by D flip-flops (13-20) and an adder (21). Data interpolated along a quadratic function curve enveloping the discrete data is obtained from the adder (21).</p> |
