Abstract

Discrete wavelet transformation (DWT) is mostly used for image processing and data compression. This paper shows that DWT may be of good use at one-dimension data processing. With certain conditions met, compared to discrete Fourier transformation (DFT) or discrete cosine transformation (DCT), transformed data provide less coefficients fit for further use. These properties are demonstrated on the data obtained from a tin dioxide gas-based sensors TGS 813 and TGS 822. Organic liquid vapors (acetone, ethanol, hexane) mixed with air were used at the tests.
