Waveguides are more difficult to install. C. Waveguides can only be used in low-power applications. D. Waveguides leak signal into the air. Student Answer: A     Answer: Incorrect Reference: 12.   Richard says "a band-pass filter can be made with a series-tuned LC-circuit." Pam says "a band-pass filter can be made with a parallel-tuned LC-circuit." Who is correct? A. Neither Richard or Pam is correct B. Pam is correct C. Both Richard and Pam are correct D. Richard is correct Student Answer: B     Answer: Incorrect Reference: 13.   For any filter, the more selective the filter is, the closer its shape factor will be to a value of A. 2. B. 100. C. 0. D. 1. Student Answer: A     Answer: Incorrect Reference: 14.   To remove pulsations from a power-supply output, you could use a A. band-pass filter. B. high-pass filter. C. low-pass filter. D. band-reject filter. Student Answer: A     Answer: Incorrect Reference: 15.   A line filter would be used to remove A. high-frequency noise spikes from an AC line signal. B. line frequencies from an alternator. C. pulsating DC voltages from a rectifier. D. low frequencies from an AC line signal. Student Answer: D     Answer: Incorrect Reference: 19.   A filter that always contains at least one tuned LC circuit that's either in series with or across the signal line is the A. constant-K filter. B. low-pass filter. C. high-pass filter. D. M-derived filter. Student Answer: C     Answer: Incorrect Reference: 6.   Which of the following is a disadvantage of the waveguide as compared to a transmission line? A. Waveguides can't be used at any of the higher frequencies. B. Waveguides are more difficult to install. C. Waveguides can only be used in low-power applications. D.

Explanation / Answer

Question 6, Answer:

Ans:D

The waveguide it is a antenna, this means that radiates signal in all directions, leaking signal into the air

Question 12, Answer:

Ans: A

Pam and Richard needs a Circuit RLC

Question 13, Answer:

Ans: C

While factor is lower, the filter it is more closer to an ideal filter

Question 14, Answer:

Ans:D

You need to remove those frequencies who generates the pulsations

Question 15, Answer:

Ans: A

Those Lines attenuate the signals radio with high-frequency

Question 19, Answer:

Ans:B

This filter only have The low Cut-Off Frequencies
