With reference to Fourier Series representation of periodic signals, consider the following statements:1.Fourier Series decomposes a periodic signal into a sum of harmonically related sinusoids.2.The coefficients of the Fourier Series depend on the fundamental period of the signal.3.Fourier Series can directly represent non-periodic signals without modification.4.Both exponential and trigonometric forms of Fourier Series are equivalent representations.Which of the above statements is/are correct?
