Abstract
A digital input is 8-fold oversampled, delay circuits to and multipliers/adders to perform a convolution arithmetic while multipliers/adders to process the oversampling data into predetermined digital basic waveforms, and continuous interpolation values can be obtained, thereby requiring no low pass filter which causes deterioration of phase characteristics, and suppressing an interpolation abortion error by setting finite interpolating functions. Furthermore, by obtaining apart of oversampling data as input data by using an AND gate , a subsequent process using the digital basic waveform and the convolution arithmetic can be performed in a very simple process.
