Define Amplitude, Waveform, and Frequency
"Amplitude is the maximum displacement from the resting position to the highest point (crest) or lowest point (trough) of a wave, indicating its energy. Frequency is the number of complete wave cycles that pass a fixed point per second, measured in Hertz (Hz), and determines the pitch of a sound or color of light. A waveform is the visual representation of a wave, showing how its amplitude or other properties change over time or position, allowing us to see its shape and characteristics."
What unit of measure is used to indicate frequency?
Hertz (Hz)

What does the Nyquist-Shannon Sampling theorem state?
"To perfectly reconstruct a continuous analog signal from its samples, the sampling rate must be at least twice the highest frequency component of the signal."
