Let x (t) = 0.8 cos(2*pi*t) + 0.15, 0= t = 1, and zero otherwise, be the input to a two bit ADC converter.
For a sampling period Ts = 0.025 sec
The a four level quantizer, corresponding to the 2 bit ADC is defined as:
delta(k)=x(nTs)<(k+1)delta -> x (nTs)= delta(k) k= -2,-1,0,1
Where x(nTs), found above, is the input and x (nTs) is the output of the quantizer. Let the quantization step be delta= 0.5. Plot the input-output characterization of the quantizer, and find the quantized output for each of the sample values of the sampled signal x(nTs).
