Let’s suppose the message x(t) is an analog signal shown in the figure below.
a) Draw the block diagrams of the system which converts the analog message signal x(t) to a pulse modulated signal.
b) Draw the sampled signal with the sampling frequency fs=2khz
c) Carry out the quantization process with the quantization level q=2^n = 8
d) Generate the PCM code words.
e) Draw the pulse modulated signal in the form of Bipolar NRZ (non-return to zero)
using the first eight digits of the code words generated in (d).
