Comparators compare two voltages and indicate which is larger.
They are commercially available as integrated circuits.
Thereby comparators can be
distinguished by their field of application...
for general applications (eg. LM311),
Comparators with extremely short switching times
Integrated circuits with multiple comparators
(eg. 2-fold LM393, 4-fold LM339),
Specialized integrated circuits
(eg. display driver LM3914, LM3915).
In the experiments, you use the following comparators...
