RC filter plays an important role in data transmission and wireless communication over bandlimited channels. It has been used as pulse shaping to control intersymbol interference (ISI) and it reduce side lobe of band power by which it also reduces adjacent channel interference. According to the previous literature [1][2], those RC filters have to equalize distorted phase characteristic. Thus, it’s cost effective and phase compensation has to be considered. In order to improve the phase characteristic of RC filter, Bernstein polynomials [3] is superior in design of linear phase filter
The paper is organized as follows. In section 2 we describe the frequency response of RC filter. Section 3 describes the approximated RC filter using Bernstein polynomials. Section 4 is the simulation results of the proposed RC filter composed of the stability test with Mihailov’s criterion and a plot of the filter by the simulator. And finally, the conclusion given in section
