i need clear ans and solve  very very fast in 20 min and thank you | 

3- What is the minimum sampling rate required for the following signal that avoid aliasing case? f(t) cos(6x t) + cos(8x t) + cos(10x t) a) 5 c) 10 d) 10x b) 5x 4- Assume that a complex multiply takes I us and that the amount of time to compute a DFT is determined by the amount of time it takes to perform all of the multiplications How much time does it take to compute a 1024-point FFT? a) 10240 s b) 5120 ms c) 5120 s d) 5.12 ms
