Choose the right answer to the question. Cut off is the slope of the log-magnitude curve from the following options, along with the detailed explanation.
- At the start of the curve
- At the end of the curve
- Near the cut-off frequency
- None of these
Answer: 4 The cut-off is the slope of the log-magnitude curve in Bode plots near the cut-off frequency.
None of these statements finds correct for cut-off is the slope of the log-magnitude curve from the following options along with the detailed explanation.
Solution
The detailed solution to the question, cut off, is the slope of the log-magnitude curve.
The cut-off rate is the slope of the log-magnitude curve close to the cut-off. The cut-off rate indicates the ability to discriminate between the signal and noise.
The cut-off frequency is the frequency at which the magnitude of the closed-loop frequency response is 3 dB below its zero-frequency value.
Hence, Option (C) is the correct answer.
