How many harmonics does a sine wave have?
A sine wave will only have one harmonic - the fundamental (well, it already is sine, so it is made up of one sine). Square wave will have an infinite series of odd harmonics (that is, to make a square wave out of sines you need to add sines of every odd multiple of the fundamental frequency).
Does a sine wave have even or odd harmonics?
The sine waveform is unique in that it doesn't have any additional harmonics; it is the fundamental waveform.
What are harmonics in a sine wave?
Harmonics are sine waves with frequencies that are integer multiples of a base frequency (f, 2f, 3f, 4f, …). They correspond to the different ways that a musical instrument like a pipe or a string can resonate to produce sound.
What waveform is made up of odd harmonics only?
Like a triangle wave, the square wave contains only odd harmonics, which is why there are peaks at 300, 500, and 700 Hz, etc.
