3.4 No problems from the textbook. Instead, complete the following: (a) In DC electronics, an operational amplifier (or simply op-amp) is a component that can be used as a linear voltage amplifier. In normal operation, the op-amp accepts a voltage signal and returns an amplified voltage signal. In this region, the output of the op-amp is a linear function of the input. However, the output voltage cannot exceed the total power supply voltage. At some point, the output signal will simply "max out" at the supply voltage regardless of the input: the op-amp then behaves like a constant function. For a particular op-amp, the output voltage V is a function of the input voltage x as de- -6 if x
