The analysis and processing of biological signals is often hampered by the contamination of these low frequency, often low amplitude waveforms by motion artifact in fluid filled catheter systems and skin electrodes, power line hum, and so on. Although noise suppression techniques have relied upon low pass filtration of the analog signals with active or passive RLC filters, even the most recent active RLC filter implementations display operational characteristics not entirely satisfactory for low frequency applications.
