By introducing which of the following, signal-to- noise ratio can be improved?
A. Small amplitude field modulation
B. Large amplitude field modulation
C. Small amplitude field attenuation
D. Large amplitude field attenuation
Answer:A
By introducing which of the following, signal-to- noise ratio can be improved?
A. Small amplitude field modulation B. Large amplitude field modulation C. Small amplitude field attenuation D. Large amplitude field attenuation
Explanation: By introducing small amplitude field modulation, signal-to- noise ratio can be improved. This is because the previous DC measurement is too noisy.
