Abstract :
The embedded zerotree wavelet transform (EZWT) coding scheme is utilized to compress transient power disturbance signals. The results of the compression and the reconstruction by this coding scheme are presented and compared with previous work. A principal adventure of this coding scheme lies in the fact that it provides for variable compression ratios.
