BC:3.2 For the discrete time function f[n] = (0.9e¯jn/3 +0.9e+j™n/3) (u[n + 4] − u[n · - Make a table of the values of ƒ [n] for values of |n| Hand sketch the following signals that are man lations of f[n] and label all nonzero values. If va are complex sketch signal strength as the magnit and label values in polar form with the angle in grees. In cases where the argument of f[] is no integer, use the value of zero for the signal.

! Required information x(t) A - The given figure is a graph of one fundamental period of a periodic function x(f). A CTFS harmonic function cx[k] is found based on the representation time being the same as the fundamental period To, where A1 = 5, A2 = -3, and To = 5. Determine the numerical value of cx[0]. The numerical value of cx[O] is

For the following sequence {3.2,-2.2,-1.5,1.4,1.89,3.3…}, Quantize it using a uniform quantizer in the range of (-3,3) with 6 levels, and write the quantized sequence.
