Score for this quiz: 220out of 220Submitted Jun 26 at 11:29amThis attempt took 65 minutes.Question 110 / 10 pts(TCO 1) The following response curve would be produced by what kind of filter?Low-passCorrect!High-passBand-passBand-rejectThe output voltage decreases with increase in frequency.Question 210 / 10 pts(TCO 1) Which of the displays shown below would be seen on a spectrum analyzer?
Correct!ABCDA spectrum analyzer displays a signal in frequency domain.Question 310 / 10 pts(TCO 1) The following response curve would be produced by what kind of filter?Low-pass
High-passBand-passCorrect!Band-reject or Band-StopA band-reject filter (also called a band-stop or notch filter) is one where a selective bandof frequencies are blocked having a minimum output while frequencies above and below the pass-band are passed having maximum output.Question 410 / 10 pts(TCO 1) The following response curve would be produced by what kind of filter?Low-passHigh-passCorrect!Band-passBand-reject
The output voltage increases with increase in frequency.Question 510 / 10 pts(TCO 2) Referring to the spectrum analyzer display below, what is the modulation frequency?5KHz10KHzCorrect!20KHz40KHzSpan = 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 KHzQuestion 6
