* * 0 Biosignals What is a signal? Signals are variations in energy that carry information . The variable that carries the information (the specific energy fluctuation) depends upon the type of energy involved. For example, if the energy is electrical, the variable is a voltage or a current, while if the energy is mechanical, the variable is force or velocity (or position). What do we use signals for? Irrespective of the type of system, its scale, or its function, we must have some way of interacting with any system of interest to us. Interaction or communication with a system or between systems is done through signals.
