If two sinusoids of the same frequency but of different amplitudes and phase angles are subtracted, the resultant is
A. a sinusoid of the same frequency
B. a sinusoid of half the original frequency
C. a sinusoid of double the frequency
D. not a sinusoid
Answer:A
If two sinusoids of the same frequency but of different amplitudes and phase angles are subtracted, the resultant is
A. a sinusoid of the same frequency B. a sinusoid of half the original frequency C. a sinusoid of double the frequency D. not a sinusoid
Explanation: If two sinusoids of the same frequency but of different amplitudes and phase angles are subtracted, the resultant is a sinusoid of the same frequency
