INTERPOLATION BASED ON WAVELET COEFFICIENTS FOR FREQUENCY MEASUREMENT

Tomasz Tarasiuk

Abstract

Presented paper concerns the problem of signal period estimation improvement by means of the wavelet coefficients. In particular, the interpolation based on the wavelet coefficient has been proposed for this aim. The method does not require virtually any additional computational power of measurement device, under assumption that the wavelet transform has been implemented for waveform analysis. In the paper results of experimental research have been presented and its merits as well as shortcomings have been discussed.
