Problem 2 Plot the frequency spectrum for the triangular wave of problem
Problem 3 Determine the mean square value of the triangular wave of prob-
Problem 4 Consider two harmonic motions of different frequencies: X1 (t) =
2 cos 2t and X2 (t) = cos 3t. Is the sum X1 (t) + (t) a harmonic motion? If so,
what is its period?
Problem 5 Find the maximum and minimum amplitudes of the combined
motion x(t) = X1 (t) + x2 (t) when X1 (t) = 3 sin 30t and x2(t) = 3 sin 29t. Also
find the frequency of beats corresponding to x(t).
