4 cards from this section. Quick, good the night before a test.
Define cascading in amplifier circuits.
Think about why we combine amplifiers.
What is the loading effect?
Consider how amplifiers interact when linked.
What is the main purpose of cascading amplifiers?
Think about what cascading means in amplifier theory.
Does loading affect the upper cutoff frequency in cascaded amplifiers?
Think about how two stages alter frequency response.
You have two CE amplifiers with gains of 20 and 30 dB, respectively. If their loading effect leads to a reduction factor of 0.5, what is the overall gain in dB?
Remember how to convert gain from dB and back.
If the upper cutoff frequency of a cascaded amplifier system is determined to be 25 kHz due to loading effects, but you desire it to be 50 kHz. What adjustments could be suggested?
Consider the role of buffering and redesigning.
