Design a limiter circuit to clip off the portions of an input voltage that fall above 3 V or below −5 V. Assume that diodes having a constant forward drop of 0.7 V are available. DC voltage sources of any value needed are available.
Answer:

Draw the transfer characteristic of the circuit shown in Figure 5-17. Assume that the LED has a constant forward drop of 2.0 V.
