Abstract

In those work in detail deal with band-pass filter, in which them as variable with frequency component used double T-network, active device network are used operational amplifier with setting unitary gain. In all circuit is emphasis on tuning, single characteristics band-pass filters, and it alternation values of one or more passive elements. To everyone circuits is also worked sensitivity analysis, describing effect variability production values resistors and capacitors on transfer characteristics filter, space is dedicated to investigation effect parametres used operational amplifier on qualities filter.
