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.
For the 66kV subtransmission network shown below, calculate the following, using a MATLAB Simulink Power System Blockset model: 1. Three phase, phase-to-phase and phase-to-earth
Function Functions: The one reason for using function handles is to be able to pass functions to the other functions-these are known as function functions. For illustration
Write a function called threshold2 (in a file called 'threshold2.m'). The function takes an arbitrary number of input variables. The first input variable, t, is required and is the
