Understanding Signal Generators and Sound Properties

What is the primary function of a signal generator?

• To measure temperature

• To change the color of light

• To supply alternating current and modify voltage and frequency

• To generate direct current

When connecting a loudspeaker to a signal generator, which output should be used?

• Low resistance output

• High resistance output

• No resistance output

• Medium resistance output

What happens to the oscilloscope trace when the amplitude of the signal generator is increased?

• The trace becomes a straight line

• The amplitude of the trace decreases

• The trace disappears

• The amplitude of the trace increases

How can you test the range of frequencies students can hear using a signal generator?

• By using a different loudspeaker

• By changing the waveform shape

• By adjusting the amplitude

• By gradually increasing and decreasing the frequency

What type of waveform produces a clear note when using a signal generator?

• Triangular wave

• Square wave

• Sine wave

• Sawtooth wave
