In this paper, and active Eight-order R band pass filter is designed and simulated at centre frequency f0 of 284KHz and quality factor Q of 30. The filter is designed from given specifications of the filter. The architecture that will be used is the multiple feedback and the gain magnitude response is simulated using MULTISIM work bench version 11.0.The simulation shows that the bandwidth of the filter at stage 3 was most selected with Bandwidth of 7.65KHz and the roll-off of the filter with values approaching -60dB/decade instead of an Eight-order which is -160dB/decade and there was a shift in the centre frequency of the filter, which is only a slight shift. The filter had a high mid-band gain that increased with each stage 1 (40.14dB) to stage 4 (87.50dB).
