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
