Inverse Discret Fourier Transform AIM: To write a program in MATLAB to perform Inverse Fourier Transform IFDT of a sequence ALGORITHM: 1. Get the sequence x(k) of length N in matrix form 2. Get the N value 3. The transformed signal: 4. x(n) = {N-1 X(K)ej2nk/N for n = 0, 1, 2, ..., N-1 ) N O small x PROGRAM: X=[4,3,2,1,0,0,0,0]; N=8; y=ifft(x,N); mag=abs(y); phase-angle(y); k=0:1:N-1; subplot(2,2,1); stem(k,X); xlabel('k'); ylabel('X(k)'); title('input sequence'); subplot(2,2,2); stem(k,mag); xlabel('k'); ylabel('magnitude'); title('magnitude sequence'); subplot(2,2,3); stem(k,phase); xlabel('k'); ylabel('angle'); title(phase sequence'); disp(y); 2. Find IDFT of each of the following sequences:i) X(k) = (1, 0, 1, 0] 1 ii) X(k) = (-4,5, 2, -3, 0, -2,3,4], 0
For the K-map where the X input is down and the Y input is across, which one of these is a simplified expression? F(x,y)=y F(x,y)=x'+y' F(x,y)=x+y' F(x,y)=(xy)' F(x,y)=x+y F(x,y)=xy
Using strcmp(s1,s2), the output is greater than 0 when s1 > s2?
Simplify the following function with a map, then implement it with a two-level NAND circuit. ?(?, ?, ?, ?) = ??′?′ + ?′? + ??? + ??′? + ?′?′?′

MATLAB: Create function files that will:generate an impulse signal δ(n-n0) over the interval n1 to n2[x,n] = impseq(n0,n1,n2)
bottom set the low-order b bits of x to 1; the others to 0. For example, if b is 3, x should be 7. Pay special attention to the edge cases: if b is 32 x should be −1; if b is 0 x should be 0. Do not use in your solution. Provided input(s): b
Look forward to hearing from you soon,
a) Write the signal x[n] in the figure in terms of step signals. b) If the unit step value of a linear time-invariant system is y[n] given above, plot the output for the input x[n] c) plot the unit impulse response of this system
