Signals can be represented as a function of the frequencies that make up the signal. This is called the spectrum. The spectrum displays the amplitude (and phase) as a function of the frequency of the sinusoidal components that make up the signal.

@zarifnazmie238 3 года назад

can the spectrum have negative value?

@alexandrosnikoloudis1905 3 года назад

Is there any way to get the graph spectrum x(f) using furrier series(no complex numbers) ?

@tharinduabeyrathna9498 2 года назад

i think yes!

@ashkrish7537 2 года назад

Without complex numbers representing a signal in frequency domain does not make sense.

@stoneshou 4 года назад

Around 7:00 for why using a function of frequency is better than a function of time.

@tharinduabeyrathna9498 2 года назад

Some times we need these spectrums for analysing purposes. When we do things like amplitude modulation we need these spectrums.

@bhaggyaumayanganasalwathur6102 2 года назад

@@tharinduabeyrathna9498 I think, this one is used for the periodic signal asymmetric condition, and when we get symmetric waveforms we cannot use this form to get the frequency spectrum, I think, we need to use exponential Fourier series to get the frequency spectrum in periodic symmetric waveforms.
