iLab Activity - Linear and non-linear spectrum analysis using MultiSim

Complete this document and submit to the DEP (DeVry eLearning Platform) dropbox.

• Copy and paste the screen capture of the MultiSim spectrum analyzer displaying the frequency spectrum of the pure, undistorted sine wave below.

[pic]

• Copy and paste the screen capture of the MultiSim spectrum analyzer displaying the frequency spectrum of the clipped, distorted sine wave below.

[pic]

• Complete the table listing the frequencies and amplitudes of the fundamental and each harmonic of the distorted sine wave below.

| |f0 |2f0 |3f0 |4f0 |5f0 |

|Frequency |1kHz |2kHz |3kHz |4kHz |5kHz |

|Amplitude (V) |6.617 V |2.977 V |142.797 mV |583.534 mV |82.953 mV |

In the table above, f0 is the fundamental frequency. 2f0 is the second harmonic, 3f0 is the third harmonic, and so on.

iLab Activity – AM modulation using Tutor*Tims

Complete this document and submit to the DEP (DeVry eLearning Platform) dropbox.

• (Part A) After using Paint to edit the image to indicate your values of EMAX and EMIN for your unique envelope. Paste the edited image of the Tutor*Tims AM envelope showing EMAX and EMIN below.

[pic]

Even though you informed us that the instruments are not 100% accurate, I was able find an estimated measurement of E-max and E-min by connecting TutorTIMS input to the Multiplier output (KXY): E-max reached 3.967Vpp and E-min reached 0.368Vpp

• (Part A, cont.) Show your calculations of modulation factor, m below.

m = Emax – Emin / Emax + Emin...
