The continuous time signal x(t) = 2*sin (2*π*100*t + π/2) + sin (2*π*150*t) + 3*sin (2*π*300*t)...

The continuous time signal x(t) = 2*sin (2*π*100*t + π/2) + sin (2*π*150*t) + 3*sin (2*π*300*t) is sampled at 500 samples per second.

Write the mathematical expression x(n) of the sampled discrete time signal. Show your work.

What are the discrete time frequencies obtained in x(n)?
