Hi Everyone,
I have a question about window comparators, which are discussed on page 862 of Electronic Principles.
I attached an image of the window comparator in question. According to the book, when vin is between 3 and 4 V, the output transistor of each comparator is cut off, so the output is pulled up to +5v? I can't imagine why this would be the case. Wouldn't each comparator just go into saturation?
Thanks in advance for any help,
Austin
