Biosignals: Acquisition And General Properties

The aim of this chapter is to provide the reader with some basic and general information related to the most common biosignals, in particular biopotentials, encountered in clinical routines. For this purpose, the chapter will be divided into two main sections. In Sect. 1. 1, we will consider the basis of bipotential recording (i.e., electrodes, artifact rejection and safety). In the second section, some general properties of a set of biosignals, will be introduced briefly. This will concern essentially, ECG, EEG, EPs and EMG. This restriction is required to ensure an appropriate coherency over the subsequent chapters which will deal primarily with these signals.
