In this paper an Eight-order Active-R Band pass filter using Biquadrtic topology at centre frequency of 284KHz and quality factor Q of 30 was Designed and simulated using MULTISIM work bench (version 11.0). the simulated response characteristics show that the filter has a low mid Band gain that decreases with each stage but recorded a positive gain at stage 3, with 13.87dB, while the Bandwidths monotonically decreased with each stage, with stage 1 having 10.82KHz, stage 2, 6.90KHz, stage 3, 5.41KHz and stage 4; 5.04KHz showing better selectivity at stage 4 (5.04KHz) at the edge of the pass band. The roll-off rate of -215.16dB/decade even surpasses that of 160dB/decade for an ideal Eight order filter indicating a very sharp roll-off exhibited by the filter. A shift in the centre frequency was observed but not out of range as it recorded 0.7% deviation from the actual centre frequency which is negligible. The filter therefore performed well and meets its specification.
