Beware that there is a “dead band” when V<sub>in</sub> is between 0.7V and -0.7V, because the voltage has not pass the cutoff voltage for either transistor. This is known as '''crossover distortion'''. |

=====Push-Pull Follower Example: A (Poor) Motor Speed Controller===== |
|||
Suppose we want to control the speed of a motor by varying the input voltage between +5V and -5V. We attempt to do this by setting put a voltage divider with a potentiometer like in the circuit below. |
