consider the following continuous time signal whose fundamental period is t=1/2.x(t) = cos(4*pi*t)y(t) = sin(4*pi*t)z(t) = x(t)y(t)
a) find the fourier series coefficients of x(t)b) find the fourier series coefficients of y(t)c) find the fourier series coefficients of z(t) (use the results of a) and b) along with the multiplication property of continuous time fourier series coefficients)d) find the fourier series coefficients of z(t) through direct expansion of z(t) in trigonometric form. compare results to part c.
(a) Calculate the length of the blades of a 1 MW wind turbine. Assume the air density is 1.0 kg/m^3, average wind speed is 15 m/sec, and overall efficiency is 25%. (b) An ideal solar cell is operating at30°C. The reverse saturation curren is0.15 mi..
