e. The voltage follower, shown in Figure Q-37, is nothing more than a buffer stage with a gain of
about 1. It has a very high input and a very low input for matching purposes.

f. The summing circuit (Figure Q-38) algebraically adds the inputs across a resistor network and
gives the sum as the output. An example of its use would be in a color generator.
