Q1: The attenuation in a waveguide near the cut off frequency isA zero
B
low
C
high
D
very high
ANS:B - low It will be very high because at the cutoff the gain factor will not be a flat band which will become flat as we move away from the cutoff because we know the waveguide is a high pass filter. So as we move away from the cutoff then we are going towards saturated gain a flat line parallel to x-axis. |
