6.2 Lab Exercise: Sifting Operations 1. Time Sifting: Write a MATLAB code for the signal s(t) = cos(wot) and right sift (postpone) the signal by 2 units and left shift (advance) the signal by 2 units as well. Choose fo 1000 Hz. Add MATLAB code and output waveform with the report. Do you notice any change in frequency or amplitude of the signal because of this operation? Give your 10 opinion Hints: x(t)-(t k). The magnitude of the sifting operation depends on the value of k. 2. Amplitude Sifting: Write a MATLAB code for the signal s(t) cos(wot)and up sift the signal by 2 units and down shift the signal by 2 units in the amplitude domain. Choose fo 1000 Hz. Add MATLAB code and output waveform with the report Do you notice any change in frequency or amplitude of the signal because of this operation? Give your opinion. Hints: x(t) = y(t) + k. You have to choose the value of k for conducting different operations in amplitude domain 3. Amplitude Scaling: Write a MATLAB code for the signal s(t) - cos(wot) and amplify the signal by 2 units and attenuate the signal by 2 units as well. Choose fo = 1000 Hz. Add MATLAB code and output waveform with the report. Do you notice any change in frequency or amplitude of the signal because of this operation? Give your opinion Hints: Y(t) = ax(t). You have to choose the value of for conducting different operations of amplitude scaling 6.2 Lab Exercise: Sifting Operations 1.
