    3 cards from this lesson. Good the night before a test.

Try these first

  1. 1.

    What is the maximum gain of a single common emitter amplifier?

    Hint

    Refer to the characteristics of common emitter amplifiers.

  2. 2.

    Define cascading in the context of amplifiers.

    Hint

    Think about how amplifiers are linked in a circuit.

  3. 3.

    What is the primary purpose of cascading amplifiers?

    • To decrease gain
    • To maintain constant output
    • To increase overall gain
    • To filter signals
    Hint

    Think about what cascading aims to achieve in terms of amplifier performance.

  4. 4.

    True or False: The loading effect does not affect the overall gain of cascaded amplifiers.

    • True
    • False
    Hint

    Recall the definition of loading effect.

  5. 5.

    Design a cascading amplifier system with two stages: the first has a gain of 150 and the second, 200. However, the input impedance of the second stage is only 50% effective due to its loading effect. Calculate the overall gain.

    Hint

    Don't forget to include the attenuation factor due to loading.

  6. 6.

    Explain how a change in temperature could affect the bias point stability of a cascaded amplifier. Provide a real-world example.

    Hint

    Consider how components in circuits respond to temperature changes.
