book on filters

[E2005]

I am looking for an excellent and practical book on filters. Would ideally prefer one book covering both analog and digital filters but if not then would get one for each. Till now my experience is limited to making analog filters.

Basically, it's a 'freeware' DSP textbook that you can download in .pdf format. Obviously it covers DSP filters.
