b) Suppose that we have 4 sources who participate in a synchronous TDM
multiplexer and that combines only three characters from each user at a time.
Note that the characters are sent in the same order that they are typed. The
first source is silent.]Draw the necessary frames with the appropriate contents
using the Interleaving concept of TDM.

a) Using the following table draw a sampled analog signal for digital signal
representation. By applying the concept of Pulse Code Modulation find the
4-bit code words and finally draw the digital signal by using MLT-3 line
coding scheme. You have to solve the problem by using step by step
formulation of normalized PAM values, normalized quantized value,
normalized error and quantization code. Assume that the sampling
amplitudes are between -40V to +40V.

b) Find the digital data from the given analog signal using Delta Modulation
(DM) technique. You can use any mean of your preference to show your work.
You can even choose to draw the waveform in your script along with the grids
(15x15) and then perform the technique. Your waveform in that case should
be roughly similar to the one given with respect to the size and shape.
