AMPLIFIERS
The electrical signal, generated by sensors, is usually at a low level of amplitude and power, so that it is necessary to amplify it before its transfer, further analogue or digital processing and visualization.
In this course we will study the characteristics of the pre-amplifiers and amplifiers for the processing of biomedical signals.
This board does not substitute the medical device under study. The results of the experiments have no medical value.
They are just for demonstration purposes.
