Analog vs Digital Filter

Another advantage results from the speed of today’s digital signal processors. Nowadays, it is quite of poles. (In the analog domain, it takes one inductor or capacitor to make one pole.) Few analog designers use more than ten poles in a filter, because it’s very difficult to make an analog filter with more than about ten poles work properly.
