Study Notes

Waves

The highest point of a wave is known as the crest.
The distance from the wave's crest to its resting position is known as amplitude.
The length of a wave between the same points of two waves is called wavelength.

Signals

Analog signals are made of waves with a continuous pattern.
Digital signals contain binary code of zeros and ones.

Sound

Sound waves can travel through solids, liquids, and gases.
The sound's pitch is determined by the frequency of the wave.

Instruments
