I'm not getting how to draw a DFT using coefficient.

c-3 =0.8597 + 0.5073 𝑖, c-2 =1.3459 + 2.6485 𝑖, c-1 =-2.8348 +13.4153 𝑖

c0 =62.289 + 120.32 𝑖, c1 =22.8537 + 7.2257 𝑖, c2 =2.1155 + 0.9273 𝑖 and

c3 = 0.0880 + 0.1215i

these are the coefficients.

Hi,

From my understanding you have a set of complex coefficients which you want to plot. You can plot the magnitude response by calculating the magnitude of each complex coefficient using the function 'abs'. Similarily , the phase response can be calculated by using the function 'angle'.

Sir, basically I have a curve and by using no of co ordinates, I need to redraw that curve by Fourier series. Please tell me how can I do it.
