ECE2006 Digital Signal Processing Lab Dr.Prakasam P Task-1 Last Date of submission: 02.08.2019 i. Generate a switched Sinusoidal signal. This is achieved by multiplying a square waveform and a sinusoidal waveform. fs = 300; t = 0:1/fs:1; offset = 1; x1 = sin(2*pi*100*t); x2 = offset + square(2*pi*10*t); a. Let’s assume the frequency of the square waveform is 2 KHz, with an amplitude of 1 volt peak-to-peak and offset of 0.3 V.Let’s also assume the frequency of the sin () signal is 10 KHz with an amplitude of 2 V peak-to- peak and no offset. b. Using subplots show all three signals. ii. Using MATLAB, generate unit impulse function

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
