  1. In a two-stage RC-coupled amplifier, if each stage has a voltage gain of 20, what is the overall voltage gain?

    Answer: 400

    Voltage gains of cascaded stages multiply, so 20 × 20 = 400.

  2. Which coupling method between amplifier stages passes DC as well as AC signals?

    Answer: Direct coupling

    Direct coupling connects stages without capacitors or transformers, passing both DC and AC components.

  3. What is the primary purpose of an emitter bypass capacitor in a transistor amplifier stage?

    Answer: Increase AC voltage gain

    The bypass capacitor shorts the emitter resistor at AC frequencies, removing negative feedback and increasing AC gain.

  4. In a multistage amplifier, the overall bandwidth compared to a single stage is:

    Answer: Narrower

    Each additional stage further limits the bandwidth, making the overall bandwidth narrower than any single stage.

  5. What does the term 'interstage coupling' refer to in amplifier design?

    Answer: Method of connecting one amplifier stage to the next

    Interstage coupling refers to the method (RC, transformer, or direct) used to connect successive amplifier stages.

  6. When using transformer coupling between stages, what key advantage does it provide over RC coupling?

    Answer: Impedance matching between stages

    Transformer coupling allows impedance transformation between stages, maximizing power transfer.

  7. In decibel notation, a two-stage amplifier with each stage providing 20 dB gain has a total gain of:

    Answer: 40 dB

    In decibels, gains of cascaded stages are added: 20 dB + 20 dB = 40 dB.
