The first difference between the two,
is the presence or absence
of active element (an amplifier. op).
That implies the presence of active filters
a gain (as in passive filters at the
you can have low attenuation (see editor's note
within the bandwidth)).
so that the student understands the lesson following the
needs to know:
- the principles of K. (I and II)
- the alternative
- The Laplace variable and its implications (Xc and Xl)
- The operational amplifier
