In this assignment, you will calculate the amplitude, frequency, and period of various signals using the following VU meter and oscilloscope displays. The videos below show the signal level being adjusted to read 0 VU, followed by -6 and then to -12 VU. Each time, the resulting signal level is shown on the scope display. You will be working with the final scope display picture in each example. In order to read the scope display, note the scope settings: TIME/DIV = .2ms; VOLTS/DIV = 1 V. This means that each division (square) represents a 0.2ms increment on the time (horizontal or x) axis, and a 1V increment on the amplitude (vertical or y) axis. There are also 5 subdivisions per square.

Look at the display on the scope.

1. What is the amplitude of the sine wave?

2. What is its peak-to-peak value?

3. What is its RMS value?


Now the level control is adjusted so that the VU meter reads exactly -6 VU.

4. What is the peak-to-peak value of the -6 VU sine wave?
Now the level control is adjusted so that the VU meter reads exactly -12 VU (or as close as we can get). An easier way to accomplish this is to set the VU meter so that 0 VU is calibrated to -6 (instead of +4) dBu, and adjust the VU meter to read -2 VU.

5. What is the peak-to-peak value of the -12 VU sine wave?

6. Based upon the measurements you made, how could you describe the relationship between a sine wave's level in VU and its level in peak-to-peak amplitude?

7. What is the period of the sine wave?

8. Based upon its period, what is the frequency of the sine wave? Show your calculation.

Now the noise generator is selected. (The VU meter is set back to its +4 dBu calibrated setting.)

Now the level control on the noise generator is adjusted so that the VU meter reads approximately 0 VU (it won't be steady, we get as close as we can).

9. What is the approximate peak-to-peak value of the noise?
Finally, a snare-drum sample loop is played. The level control on the snare drum is adjusted so that the VU meter reads approximately 0 VU.

10. What is the approximate peak-to-peak value of the snare drum? If the peak-to-peak values of the noise, snare drum, and sine wave are different, how would you explain the difference?
