A periodic signal x(t) is shown in the figure. The fundamental frequency of the signal x(t) in Hz is ___

x (t) = cos (1.2 π t) + cos (2 π t) + cos (2.8 π t) .

x (t) = (1 + 0.5 cos 40 π t) cos 200 π t

f (t) = 20 + sin (\frac{π}{7} t + \frac{π}{3}) + 5 sin (\frac{5 π}{6} t - \frac{π}{4}) - cos (\frac{6 π}{5} t - \frac{π}{6})

\frac{π}{a} r a d / s e c .

f (t) = 1 + 2 c o s (π t) + 3 s i n (\frac{2 π}{3} t) + 4 c o s (\frac{π}{2} t + \frac{π}{4})
