If a low-pass filter is set at 2200 MHz, which of the following signals would be allowed to pass through?
A) 2400 MHz
B) 1500 GHz
C) 1000 MHz
D) 23000 KHz

Quizplus · Accepted Answer

A low-pass filter allows signals with frequencies lower than its cutoff frequency to pass through while attenuating higher frequencies. Since the low-pass filter in this question is set at 2200 MHz, signal C with a frequency of 1000 MHz would be allowed to pass through while signals A, B, and D would be attenuated.
