DISCRETE FOURIER TRANSFORM
AIM
Obtain the 1D DFT and plot the phase and magnitude plot of DFT of the sequence.
THEORY
DFT is the frequency domain representation of a discrete digital signal. The DFT of a sequence x(n),with length N is given by the following equation
N
X(k)=∑ x(n)exp(-j2πkn/N)
n=0
OBSERVATIONS
ENTER THE NUMBERS : [1 2 3+4i 6-8i 5]
y =
17.0000 - 4.0000i 2.9354 + 7.8526i -13.2946 - 2.3259i 9.5307 - 0.1463i -11.1715 - 1.3805i
RESULT
Obtained the DFT of the sequence and plotted the magnitude and phase response.
