-
Period
the amount of time, in seconds, a signal needs to complete one cycle
-
Frequency
refers to the number of cycles per second, measured in Hertz
-
-
Wavelength
is the distance, in meters, for one cycle as it travels through a medium
-
-
Fourier theorem - any composite signal can be represented as a combination of simple sine waves with different frequencies and amplitudes
