sine wave
mathematical curve that describes a smooth repetitive oscillation; continuous wave
carrier wave
waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information
biorhythm
pseudoscience - the attempt to predict various aspects of a person's life through simple mathematical cycles; not to be confused with scientific term "biological rhythm"

square wave
type of non-sinusoidal waveform
sawtooth wave
type of non-sinusoidal waveform
triangle wave
non-sinusoidal waveform named for its triangular shape
continuous wave
method of radio transmission, in which a sinusoidal carrier wave is switched on and off. Information is carried in the varying duration of the on and off periods of the signal, e.g. by Morse code
crest factor
peak divided by the Root mean square (RMS) of the waveform
