ABSTRACT
Measurement systems are used to detect an input, transduce the signal and display it in a form that can be used by an interpreter. They are made up of the following: input, transducer, transmission path, conditioning unit, display unit and output. Measurement systems can either be analogue or digital. Damping describes the resistance of a system to oscillation resulting from a change in the input. In the perfect measurement system, any change in input would be instantly and accurately reflected in the output. Calibration is a process in which the output of a measuring device is compared to a standard of known units of measure to determine the accuracy of the measuring device. The components of a measurement system will oscillate at their own natural frequency. Imagine that healthcare professionals are able to give energy to the system at the perfect moment to allow us to increase the amplitude of these oscillations.
