Figure 4.4. A transistor is labeled beta = 100. The emitter is grounded. There are two terminals labeled V in. The bottom one is grounded and the top one goes to one end of a resistor labeled R 1, 6.8 k ohms. The other end goes to the base of the transistor. A resistor labeled R 2, 1.0 k ohms connects from the base to ground. The collector goes through a 150 ohm resistor to plus 12 volts. End verbal description.
