Matlab Problems: M1 (10): sin wave simulation Use the following codes, and answer the questions. Paremeter setting A = 1; % Amplitude f = 1; %frequency P=0; %Phase time 1.5; time duration = N = 1000; Sampling number = t 0:time/ (N-1): time; Generate sin wave s A*sin(2*pi*f*t+P); Draw figure plot (t,s) grid on xlabel('Time') ylabel('Amplitude') Questions: 1. Run the code and plot the figure; what is the period of the output signal? 2. Change the A= 0.5, then run the code; what is the root mean square voltage of the signal? 3. Change the f=2, then run the code; what is the period of the output signal? 4. Change the P-pi/4, then run the code; what is the value of the single at time = 0? M2 (10): Addition of frequency components Now, use the code provided before to generate 2 sin waves. 5,(t)=sin(2x ft) $₂ (1) = ½ sin (273 ft) Question: 1. Draw the two frequency components. 2. Add the two frequency components together and draw it.
