An analog signal whose voltage is varying between 0V to 2V and it is given as input to PCM with midriser type quantizer of =0.5.

An analog signal whose voltage is varying between 0V to 2V and it is given as input to PCM with midriser type quantizer of Δ=0.5. Let x[k] = {0.2, 0.7, 1.3, 1.7} be the sample values of the given analog signal. 

a. Find the Quantized signal xq[k]. 

b. Design an encoder for the above system and encode the xq[k]. 

c. Draw NRZ Unipolar and Polar signaling format for the encoded signal.
