Q3. Find the following for x[n] (assume all other sample values are zeros): (4 Marks) x[n]={5.50,1.50,2.5],0.10,5.90,6.60,0.5,4.80,1.2+6j,0.5,0} (a) Range of values of n ? Explain how (b) Duration of x[n] ? Show how (c) Dimension? Show how? (d) is x[0] anti-causal? Why? (e) Magnitude of x[3] ? Show how (f) Phase of x[2] ? Show how (g) If the arrow is shifted to 5.5 then is the sequence still anti-causal? Why? (h) Find the size of x[n] for p=x ? Show how Q4. Write the Euler's formula and explain its benefit.
