PULSE CONVERSION
The events monitoring systems such as the frequency of the cardiac pulsations, the breathing frequency, etc., require that an analogue signal be converted to pulses and visualized on a display in order to be measured.
In this course students will study some circuits for analogue to pulse conversion, sound indicator and analogue frequency meter.
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.
