Two Dimensional Graphs and Matrix Implementation in MATLAB

Draw graphs of the functions

• Y1= cos (πt);
• Y2= sin (2πt);
• Z=Y1+Y2 where 0≤t≥5

Draw graph of the given function

𝒀 = 𝒆^(𝒏𝒙) On interval -1 ≤ x ≤ 1 for n=1, 2,. . 4.

Use Sub-plots.

Draw graph of the given function

Y=t. sin (3t);

Where t is an input by the user to the function.

Write a function row operation (A), Where A is 3x3 matrix [1,2,3;4,5,6;7,8,9]. The function should perform following tasks

• Add Row1 and Row3
• Subtract Row3 and Row1
• Multiply Row1 and Row2
• Divide Row2 and Row1

Speech Processing Using MATLAB

In order to get voice signal in MATLAB use built-in function for recording voice signal for 10 seconds.

Add and subtract both voice signals with duration of your choice.

Flip and convolve (Correlate) the second signal with the first signal.

Implement Discrete Time Signal (LTI System) Using MATLAB

Whether the system is linear or not.

Y[n] = x[n] + 4x [n-1]

Whether the system is linear or not.

Y[n] – 2Y [n-1] + 3Y [n-3] = 3x[n] + 4x [n-1]

Whether the system is Time invariant or not.

• Y[n] = x[n] - x [n-1]
• Y[n] = n x[n]

Whether the system is Time invariant or not.

Y[n] = 3x[n] + 5x [n-1] + 10x [n-4]

Fourier Transform and Spectral Analysis in MATLAB

Create an analog signal with component frequency at 15 Hz and 40 Hz with fs=200. i.e. Analog signal (y) = 5xSin (2π.f.t) Using FFT analysis show its magnitude and frequencies in graph.

Create an analog signal with component frequency at 20 Hz, 35Hz and 40 Hz with fs=200.And Inject random Gaussian noise. Then compute the frequency components and its magnitude.

Find DFT of the following signal and plot the result a = [1 1 2 2] where a is a discrete time signal. By Taking IFFT verify if ‘a’ is regenerated or not?

Use audio signal of your own choice and find the fundamental frequency of that signal.

• DSP Lab two code
• Take FFT (only magnitude) of my recording. Than plot.
• Take IFFT (only magnitude) of my recording for original recording. Then plot.
• Use fs=200, fftshift command, proper labeling and find power. (P=abs(y). ^2/N).
