(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 get 100 samples.
Let the frequency axis run from 0 to 2 in pi units. Use 500 frequency points to plot the DTFT.
(b) Using Matlab, overlay on the plot the magnitude of the DFT coefficients Xk vs frequency in pi units for a 100 point transform of this set of samples.
(c) Find the DFT frequency resolution. On the plot, indicate where f1 and f2 are on the frequency axis.
(d) Now use 100 sample points of the waveform with no zero padding in the DFT magnitude plot. Annotate this plot and indicate the frequencies f1 and f2 present in the wave form.
(e) Title the plots and label the axes appropriately. Submit the plots along with the source code.
Write the iterative Newton root nding function from lecture to be recursive. The function declaration should be root = newtonRec(f,df,x,tol). The inputs to the function are: ?
Consider the shaft-rotor system shown in Figure. Write down the equations of motion. Taking I= 1 kgm 2 and k=10 kNm/rad, for two special cases (α =0.5 and α = 1000) find as many
Ant Colony Optimization for Optimization of Route path taken Ant Colony Algorithm is a potential candidate for coupled, 3D optimisation. Ant Colony Algorithm enjoys the overall
How can I separate a row vector into groups.
User-Defined Functions which return a Single Value: We have seen the use of many functions in the MATLAB. We have used many built-in functions like fix, sin, abs, double, and
Functions which return More than one Value: Functions which return one value have one output argument. The Functions which return more than one value should rather have more t
Types: Each and every expression, or variable, has a type related with it. The MATLAB supports numerous types of values that are known as classes. A class is necessarily a com
