Figure 4.10. The bottom of the input is grounded. The top input terminal goes through a capacitor labeled C 1 to the base of an NPN transistor. The base also goes through R 1 to V CC. The base also goes through R 2 to ground. The collector goes to V cc. The emitter goes through R 3 to ground. The emitter also goes through C 2 to the high output terminal. The other output terminal is grounded. There is a resistor labeled R 4 connected from one output terminal to the other. End verbal description.
