Multichannel Spline Interpolation of Discrete Signals
MetadataShow full item record
This paper presents the multichannel sampling of a continuous-time signal with division of its frequency band into a few sub-bands. It deals with the combination of this sampling method and spline interpolation with the aim of utilizing their advantageous properties,i.e. low sampling frequency of the multichannel sampling and small error in the spline interpolation series. On the basis of the derived multichannel interpolation series by using of the spline functions, the simulation of two and three channel interpolation of the discrete signals was done.
