A 12-point sequence is x (n) defined as x(n) = { 1, 2, 3, 4, 5, 6, 6, 5, 4, 3, 2, 1}. Write MATLAB programs to
(a) Determine the DFT X (k) of x(n) and plot (using stem function) its magnitude and phase.
(b) Determine the DTFT X (ejω) of x(n) and plot the magnitude and phase of X(ejω). You need to properly define the resolution of X(ejω) in the frequency domain.
(c) Verify that the above DFT is the sampled version of X(ejω). It might be helpful to combine the above two plots in one graph using the hold function.
(d) Is it possible to reconstruct the DTFT X(ejω) from the DFT of X(k)? If possible, give the necessary interpolation formula for reconstruction. If not possible, state why this construction cannot be done.
The programs generating the plots should be provided.
This can be done from the command line or from a makefile. You require a script (filename.m). Just type at the command line, or contain in the makefile: matlab
Use MATLAB and a method based on linear predictive coding for the restoration of a clipped voiced speech signal. My proposed algorithm is based on linear prediction where a reco

Use Taylor series to derive the form of the truncation error of the approximation Suppose f € C3. Given that the roundo error has the similar form as in the Forward D
Simple Related Plot Functions: The other functions which are useful in customizing plots are the figure, clf, hold, leg-end, and grid. The short description of such functions
Create a function using mat lab to generate a sinusoidal signal. The parameters of the signal should have an Amplitude = 100, frequency = 100Hz, initial phase = 0, sample rate = 50
(a) Using Matlab, find and plot the magnitude of the DTFT of 10 samples of x(n) for n=[0:1:9] of x(n) = cos(2*pi*f1*n) + cos(2*pi*f2*n) for f1=0.22 and f2=0.24 and pad zeros to ge
