EEL3135 Dr. Fred J. Taylor, Professor “Pop” Quiz #1 (10 minutes) Name_________________________________ Student Number________________________ A signal x(t)=sin(2 π f 0 t), f 0 =900Hz, is sampled at 1,200 Sa/s rate to create a time-series x[k]. The time signal x[k] is presented to an ideal Shannon sin(x)/x interpolator to create a continuous- time signal y(t). Mathematically, what is y(t)?
