An oscilloscope is a tool used by many electronics technicians and
engineers, and it measures and displays ________________ signals.
Amplitude, DC offset, phase shift, period, and ________________ are
useful signal characteristics that can be measured with an oscilloscope.
An oscilloscope typically displays ________________ on the horizontal
scale and ________________ on the vertical scale. ________________
and DC offset are two quantities related to voltage that are measured
differently for different signals.
For a pulse train, the amplitude is the voltage between the high and low
signal. For a _________________ triangle wave, as with the sine wave,
the amplitude is the maximum deviation from the center line of the signal.
For the sine wave and triangle wave, the ________________ is the voltage
between the center line and 0-volts.
The frequency is the number of times a waveform repeats itself and the
________________ is the amount of time the waveform takes to repeat
itself. The frequency is the ________________ of the period.
Time varying voltage signals sent to a speaker can result in audible tones.
Adjusting the ________________ of a voltage signal adjusts the volume
of the tone.

Musical notes are represented by ________________ waves oscillating at
certain frequencies.
(PWM) sent to the input of an ________________ to generate a sine wave
at the output.
