Abstract: In this paper, an active eighth order band-pass filter is implemented. The filter has a center frequency of 15 kHz and roll-off rate of -80dB/decade. The architecture used is the Sallen-Key configuration. The filter parameters and values for the passive components were calculated and the gain magnitude and phase output response is then analyzed with MATLAB software. The simulation shows that the filter has high gain, a wide bandwidth and a good roll-off at the pass band.
