Abstract

In this paper, a new concept of an adaptive filter is presented. The filter itself is an analog circuit that consists of two operational amplifiers and four multipliers. The filter characteristics can be controlled and modified using two separate reference inputs. The references are generated by the microcontroller, thus having the opportunity to choose waveforms that are dictated by the operating conditions. Besides the results, some problems and possible solutions are also presented
