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?
💡 Hint: 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?
💡 Hint: Consider the role of buffering and redesigning.
