Score for this quiz: 220 out of 220 Submitted Jun 26 at 11:29am This attempt took 65 minutes. Question 1 10 / 10 pts (TCO 1) The following response curve would be produced by what kind of filter? Low-pass Correct! High-pass Band-pass Band-reject The output voltage decreases with increase in frequency. Question 2 10 / 10 pts (TCO 1) Which of the displays shown below would be seen on a spectrum analyzer?
Correct! A B C D A spectrum analyzer displays a signal in frequency domain. Question 3 10 / 10 pts (TCO 1) The following response curve would be produced by what kind of filter? Low-pass
High-pass Band-pass Correct! Band-reject or Band-Stop A band-reject filter (also called a band-stop or notch filter) is one where a selective band of frequencies are blocked having a minimum output while frequencies above and below the pass-band are passed having maximum output. Question 4 10 / 10 pts (TCO 1) The following response curve would be produced by what kind of filter? Low-pass High-pass Correct! Band-pass Band-reject
The output voltage increases with increase in frequency. Question 5 10 / 10 pts (TCO 2) Referring to the spectrum analyzer display below, what is the modulation frequency? 5KHz 10KHz Correct! 20KHz 40KHz Span = 8 0 KHz. There are four divisions and starting frequency is 160 KHz each division corresponds to 20 KHz, upper side frequency corresponds to third division so it is 160 KHz+60KHz = 220 KHz, Carrier frequency in the center = 200 KHz, modulation frequency = Upper side frequency – Carrier frequency = 220 – 200 = 20 KHz Question 6
