this part, a continuous-time signal (t in sec) is considered as follows a > 0 11 Ph the frequency (2) x(t) = a sinc(at), where sinc(t) sin(t) = t with its Fourier Transform result as F{sinc(t)}(f) = rect(f). 1. [5%] Find the size (absolute integral), energy, and power of the signal x(t). [Hint: Parseval T X(+) Sing/x+ 0152.
