Bio-electric signals convey information and phenomenon of the physiological activities of organisms, such as gene, protein sequences, neural, and cardiac rhythms. Various types of bio-electrical signals are extensively used for diagnostics as well as therapeutic interventions. Bio-electrical signals are low-amplitude, low-frequency and numerous unique properties (spiking, small oscillation, local field potential interference). The original signal's amplitude is so small that directly lower the output resolution of the analog to digital converter (ADC). Furthermore, the detected signals are corrupted with, local field potential, white noise, system noise, and other interference, so the relevant information could be easily missed during the digitization. …
