2 A Continuous Time Periodic Signal Is Given As Follows Ta T 16 Cos 27fit 5 8sin 2xf2t Where Fi 1 5 Khz 1 (6.91 KiB) Viewed 31 times
2 A Continuous Time Periodic Signal Is Given As Follows Ta T 16 Cos 27fit 5 8sin 2xf2t Where Fi 1 5 Khz 2 (18.05 KiB) Viewed 31 times
(2) A continuous-time periodic signal is given as follows: Ta(t) = 16 cos (27fit + */5)+8sin (2xf2t), where fi = 1.5 kHz and f2-2 kHz.
(e) Find and plot 1(1), the sampled version of Ia(t). (f) Describe how to used i(n) and an appropriate window to display the spectrum of the orig- inal continuous-time signal Ia(t) such that all its frequency components are well resolved. Plot the magnitude spectrum for verification. Also, determine the minimum duration needed in seconds. Finally, show the block diagram of the system.
