Capture and processing of analog signals whose level is a function of frequency, usually requires the use of frequency dependent circuits. They often use active 4-poles that implement the integration or derivation of the processed signal. Steady and largely standardized operational amplifiers involved in the function of integration and derivation amplifiers are described in numerous publications. This paper presents new possibilities for the involvement of bipolar circuits with operational amplifiers. The proposed connections are primarily intended for applications in the field of measurement technology for laboratory and process measurement.
