Both the Fourier Series and the Discrete Fourier Transform are
calculated using summation. Explain the key differences in what the
inputs each of the Fourier Series and the DFT are AND the
requirements the inputs.
Develop the 8-point Discrete Fourier
Transform (DFT) using butterfly diagrams for the discrete input
sequence x(n) = {1, 2, 3, 4, 4, 3, 2, 1} using radix-2 Decimation
in Frequency - Fast Fourier Transform (DIF-FFT)
algorithm.
Given the following functions, can you have the corresponding a)
Fourier series, b) Fourier transform and c) Laplace transform? If
yes, find them, if not, explain why you can not.
A, x(t) = -1+cos(2t) +
sin(pai*t+1)
(4-1)
B, x(t) = 2d(t) cos(2t) +d(t-1.5p)
sin(2t)
(4-2)
C, x(t) = 1+cos(1.5t) +
cos(4t)
(4-3)

Using Matlab Simulink, find Fourier transform of the following
signal;
?(?) = 2 + ∑
1 ?
sin (20???)
4
?=1
.
Set simulation stop time = 20 seconds, sample time = (1/1024)
seconds, buffer size =1024, and frequency range in Hz for the
vector scope is −100 ≤ ? ≤ 100
(A) Explain what a Fourier Transform (FT) does in plain
English.
(B) Explain the advantages of a FT instrument over a constant
wavelength diffuse instrument.
a) Find the discrete Fourier series (DFS) representation of
x((n))10, where 10 denotes the period and x(n) is given by:
?(?) = { 1, ??? 0 ≤ ? ≤ 5
0, ??? ??ℎ?? ?
b) For the following two causal sequences (both starting at n =
0), find the circular convolution of minimum size that will produce
the same result as
h(n)*x(n). h(n) = {1, 1, 1, 1},
x(n) = {0, 0, 1, 1}
sir I want to make discrete time Fourier series on GUI
MATLAB can any one tell me step by step procedure or coding for
Discrete time Fourier series on GUI? pleaseeeee
