Abstract
A data interpolating method capable of reducing an operation volume without the occurrence of a truncation error. Each of four step function generators generates a preset step function. Multipliers each multiply step function values output from relative step function generators by discrete data values held cyclically in data holding sections. An adding unit adds together the multiplied results output from respective multipliers in response to the respective four discrete data and the added values is integrated twice by integrators, an interpolation value between the discrete data being then output from the second-stage integrator.
