Hello, I am finding it difficult to understand how the switching voltage is calculated with a different reference voltage in part b of the question I posted. The professor has provided the solution but I don't understand the reasoning behind it.
For example, when calculating V+ and V-
V+ = ( Voutputhigh - Vref ) . R1/R2 + Vref
V- = ( Voutputlow - Vref ) . R1/R2 + Vref
What is happening in this equation?
Another question
Is R1/R2 equal to β?
I thought the gain of an ideal op amp was infinite, so why do we calculate β?
Any help would be greatly appreciated,
Thanks
