Challenge Problems
Push your limits with advanced challenges
An audio amplifier has a THD of 3%. If the original signal is at 1 V, what is the total distortion in comparison to the desired clean output?
💡 Hint: Calculate using the formula: Distorted output = Original output × (1 + THD).
If an op-amp exhibits a slew rate of 10 V/μs, how fast can it respond to a 30 V step input? Calculate the time taken for the output to reach that value.
💡 Hint: Relate the problem to how long it takes to travel a certain distance.
