Which waveform contains only the fundamental frequency with no harmonics?
Answer: Sine wave
A pure sine wave consists of a single frequency with no overtones or harmonics.
A sawtooth wave is known for containing which set of harmonics?
Answer: All harmonics, both odd and even
A sawtooth wave contains all integer harmonics, giving it a bright, buzzy tone.
Which waveform's harmonics roll off faster, giving it a softer, more mellow sound than a square wave?
Answer: Triangle wave
The triangle wave contains only odd harmonics that fall off steeply, producing a soft tone.
Pulse-width modulation (PWM) is most directly applied to which waveform?
Answer: Square/pulse wave
PWM changes the duty cycle of a pulse/square wave to create movement and tonal variation.
What characteristic harmonic content does a square wave have?
Answer: Only odd harmonics
A symmetrical square wave contains only odd harmonics, giving it a hollow, woody tone.
Which classic synthesizer waveform is the best starting point for emulating brass and string sounds because of its rich harmonics?
Answer: Sawtooth wave
The sawtooth's full harmonic spectrum makes it ideal for bright brass and string patches.
White noise is best described as containing what?
Answer: Equal energy across all frequencies
White noise has equal energy per frequency band, useful for percussion and wind effects.
