Introduction

Recording biological signals provides a primary doorway to the understanding of how the human body behaves under normal and pathological conditions. The rhythmical activity of the heart, for example, might be studied by measuring the difference of electric potential between two appropriate locations on the body surface. Similarly, bodily temperature and metabolism may be monitored with the use of specific devices. Once acquired, these biological signals demand proper treatments to unveil relevant information. Standards for the conditioning, acquisition and processing of biological signals are consolidated into widespread techniques of measurement1-3.

The possibility of studying the activation of skeletal muscles, through the recording of electrical potentials produced during muscle contractions (the e...
