Abstract
Disclosed is a waveform analyzer, which inputs measured data of an electronic device to be analyzed; generates an orthogonal analyzing wavelet; produces wavelet-analyzed components in which the measured data is wavelet-transformed into a plurality of wavelet spectra by using the orthogonal analyzing wavelet, thereafter the plurality of wavelet spectra are inverse-wavelet-transformed to produce the wavelet-analyzed components; and adds up a component with an order corresponding to a desired filter characteristic of the wavelet-analyzed components to get a filtered waveform.
