Discussion
Match each measurement with what it reveals.
List I
A. Square wave edge rounding
B. Square wave top droop
C. Square wave edge overshoot
List II
P. The high-frequency limit
Q. The low-frequency limit
R. A peaked response near the band edge
Select the correct match.
Answer: D
The pairing is A-P, B-Q, C-R. One test signal reports on three independent properties, each visible in a different part of the waveform: the edges carry the high-frequency content, the flats the low, and overshoot betrays excess gain near the band edge. That is why a square wave is reached for before a sweep generator when an amplifier's behaviour is unknown.
