Question

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).
