Hello,
can someone explain to me basically the difference between the ' haar' and ' db2' wavelets (parameter for the wfilters function) that can be found here?
Also, in the Wavelets column from the table (shown on the same webpage - wfilters), it is written 'db1' or 'haar'. Does this mean the wavelets 'db1' and 'haar' are the same?
Note: I don't know much about wavelets, I'm just starting to learn about it.
Thanks in advance
