a spectrum is calculated by performing?

Fourier analysis

Fourier transform

any waveform can be analyzed or broken down into a series of sinusoids, each with a specific frequency, amplitude and phase

is a triangle wave composed of even or odd harmonics?

odd

Can we do Fourier analysis with white noise?

yes, has power over frequencies

best example of complex wave with harmonic multiples

note on piano

amplitude of white noise at any given time is?

random

average spectral density of white noise is?

flat

why is white noise called white noise?

because it consists of a full spectrum of waveform frequencies, similar to how white light is a combination of a full spectrum of visible colors
