Abstract
A signal interpolation apparatus in which first signals of the same type as a first signal selected and taken out at a given time point from several types of signals having a predetermined correlationship with an original signal are taken out from a signal source by a sampling device, and second signals of a first type different from the first signals are taken out from the signal source by a second sampling device. The output signals of the first and second sampling devices are converted into a predetermined form respectively, and a coefficient of the conversion signal of the second sampling device against that of the first sampling device is determined. An output signal of the second sampling device is interpolated on the basis of the coefficient.
