Electronics About active filter, very easy. ¿is it posible to create an
negative-frecuency filter? I mean a pass-band filter from -3000Hz to +3000Hz.
I told my mates it is imposible, because there is no negative frecuencies. And in the calculus of de cut frecuencies with the opams 1/( 2*pi*root(bla bla bla)) it is imposible to obtain a result since there is a root on that.
