1.
Imagine a sine wave on the oscilloscope screen that had an
amplitude of 4V and a period of 2ms. If you turn the time/division
knob to something larger, will one number change, both, or neither?
If one does change, does it increase or decrease?
2. When measuring amplitude of a wave, why is it useful to
measure from the bottom to the top of the wave?
3. What is the mechanical audio signal that the microphone
receives changed to...
