1. The DTFT of a discrete-time signal x[n] is given by X(e") = E z[n]e=jwn, n=-00 which is called the DTFT analysis equation. Write a MATLAB function that performs DTFT analysis equation for the signal given below. Create the x[n] signal by defining the appropriate ranges for n. Calculate the DTFT, plot magnitude and phase of X(ei@) by using abs and angle functions of MATLAB. x[n] = 0.2"u[n – 4] + 0.4"-1u[n] %3D
