HELP WITH QUESTION 4. but you need number 2 and 3 to answer it.

2. Generate one cycle of the square wave similar to the one shown above in a 500-point MATLAB array. Determine the RMS value of this waveform. When you take the square of the data array squaring point by point (ie, x2). be sure to use a period before the up arrow so that MATLAB does the 3. Use Equation 24 to analytically determine the rms value of the waveform shown below with amplitude of 1.0 V and a period 0.5 s. (Hint: use the symmetry of the waveform to reduce the calculation required.) 3.0 0.25 0.25 3.0 Time (s) 4. Generate the waveform shown for Problem 3 above in MATLAB. Use 1000 points to produce one period. Take care to determine the appropriate time vector. (Constru the function in MATLAB is more difficult than the square wave of Problem 2, but can still be done in one line of code.) Calculate the rms value of this waveform as in Prob lem 2. Plot this function to ensure you have constructed it correctly
