the amplitude at 70.7% of the maximum value
the amplitude at 90% of the maximum value
the amplitude at 1.41 times the maximum value
the maximum positive or negative value E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: D. the maximum positive or negative value.
A sine wave is a periodic function of time that has the form of a sine curve. The peak value of a sine wave is the maximum positive or negative value that the function takes on.
Option A is incorrect because the amplitude at 70.7% of the maximum value is called the root mean square (RMS) value.
Option B
is incorrect because the amplitude at 90% of the maximum value is called the half-power point.Option C is incorrect because the amplitude at 1.41 times the maximum value is called the peak-to-peak value.
Option E is incorrect because the maximum positive or negative value is the peak value.
