If you used a single positive supply,
a Hi would approach the value of the
power supply. A Lo will be approximately zero. The output can swing positive AND neg. only if you
used a p0s. AND a neg. supply. The Hi
would be almost equal to the pos. supply and the LO will be almost equal
to the neg. supply.
In Circuits lab, we had to construct different types of operational amplifiers. The inverting and summing amplifiers produced similar output voltage to the calculated ones but were not negative. I was just wondering why they didn't reverse the sign in the experiment?
