Limiting action happens in series when a diode
is________ and in parallel when a diode
is________. - correct answer- Reverse biased,
forward biased.




What is the purpose of a diode limiting
circuit? - correct answer- To limit amplitude
of the input.




What do clampers do? - correct answer- Add DC
to AC signal.




A transistor in a Common Emitter transfers an
internal resistance from a low resistance in
emitter base to? - correct answer- High
resistance in collector base.

When does cutoff occur in a Common Emitter? -
correct answer- When Emitter PN junction is
reversed.




A Common Emitter has a gain of how much? -
correct answer- 10




How does a Common Emitter affect the phase of
an input signal? - correct answer- It inverts
the input 180° (flip)




A Common Collector has a gain of how much? -
correct answer- 1 (no phase inversion)




A Common Base has a gain of how much? -
correct answer- 10 (no phase inversion)




How do transistor amplifiers operate? -
correct answer- By an AC input signal changing
base bias.
