The design of active RC filter
Summary : RC active wave filter is a kind of signal processor, its main function is to draw the useful signal, meanwhile , suppress the passing of the interfering signal. Introduce the basic composition module of RC active wave filter , including electric current mirror , amplifier , addition device , integrator ,etc. at first in the design, recommend of different wave filters difference approach method secondly, active frequency of wave filter vary and analysis of sensitivity of wave filter. Also introduced characteristic , function and its application in the wave filter design of low steps that the electric current feedbacks the operation amplifier briefly finally. Keyword: Active wave filter A characteristic frequently
By frequency Sensitivity The electric current feedbacks the operation amplifier
