Two bit Analog -to -digital converter-MatLab (711)
Let X(t)= 0.8 cos(2*pi*t)+ 0.15, 0<=t<=1, and zero otherwise, be the input to a 2-bit analog-to digital converter.
The four level quantizer corresponding to the 2-bit ADC is define as
kDelta<= x(nTs) <(k+1) Delta --> x'(nTs) = kDelta k= -2,-1,0,1
where x(nTs), found above, is the input and x'(nTs) is the output if the quantizer. Let the quantization step be Delta = 0.5. Plot the inpu-output characterization of the quantizer, and find the quantized output for each of the sample values of the sampled signal x(nTs).
