Exploring the Properties of Sinusoids

What happens when the amplitude of a digital audio signal exceeds the maximum digital limit?

• The signal frequency increases

• The signal undergoes digital distortion or clipping

• The signal is unaffected

• The signal is enhanced

What is the standard unit of measure for frequency?

• Hertz

• Watt

• Decibel

• Ampere

How many cycles per second does a 10 Hz wave complete?

• 1000 cycles

• 1 cycle

• 10 cycles

• 100 cycles

What property of audio is primarily affected by changes in frequency?

• Pitch

• Duration

• Loudness

• Phase

How is pitch represented in the wave equation?

• By adjusting the amplitude

• By adding a frequency factor in the sine function

• By altering the phase

• By changing the time period

What is the approximate wavelength of a 100Hz wave, given the speed of sound is 343 m/s?

• 3.4 meters

• 34 meters

• 340 meters

• 0.34 meters

What effect does phase have when a single wave is played?

• It has no audible effect

• It alters the loudness

• It changes the pitch

• It modifies the wavelength

What occurs when two waves are exactly out of phase by PI radians?

• Their speed increases

• Their frequency doubles

• They cancel each other out

• They amplify each other

What can be adjusted in the wave equation tool provided in the link?

• Amplitude, frequency, and phase

• Only the amplitude

• Only the phase

• Only the frequency

At what frequency can the narrator no longer hear sound?

• 10,000 Hz

• 18,500 Hz

• 20,000 Hz

• 15,000 Hz
