Magnitude and phase spectrum with example

[@yaboimdaro]

For anyone looking for an explanation to how he write 1 to the magnitude spectrum for all signals, it is because when you write cosw as (e^jw + e^-jw) / 2 = so that there comes a 1/2 multiplied by 2 gives 1 magnitude.

I'm on the spectrum!

[@saeed1367]

Thanks for great video! what is the difference of auto-spectral, amplitude spectra and cross-spectral density? is amplitude and Magnitude same?

[@funcepts2116]

Auto-spectral density is the Fourier transform of the Autocorrelation function. It’s also called the power spectral density (PSD) - See Weiner-Khinchine theorem. Similarly the Cross spectral density (CSD) is the Fourier transform of the cross-correlation function. CSD gives a measure of spectral correlation in a pair of signals. Magnitude spectrum is same as amplitude spectrum but without the sign. A negative amplitude is equivalent to a magnitude with a 180 degrees phase shift. The 180 degrees phase shift corresponding to a minus sign is usually represented in the phase spectrum.

How to find magnitude, frequency and phase if sequence representing one period of signal given.

[@funcepts2116]

DTFT is used for discrete signals. For discrete periodic signals, DTFT is reduced to DFT which is used to compute over one period.
