Draw a plot of a quantized waveform for 3, 8, 16 bits 2's complement format.

Answer #1

Given numbers are 3,8,16 and Representation of these numbers in 8 bit format

3=00000011,,8=00001000 and 16=00010110.

2's complement of 3=11111101.

2's complement of 8=11111000

2's complement of 16=11101010.

For getting 2's complement of the number,First apply 1's complement and then add 1 to the 1's complemented number.

Quantizer converts the discrete signal into digital signal.

Here,For representing signal draw high level for 1 and low level for 0.

Now,I am taking Return to zero signaling for drawing wave form.After each bit ,wave goes to zero.

**Waveforms**: 2's complement form

**3 1 1. 1. 1. 1. 1. 0. 1.**

** ________________________ ____**

** |___0__|**

**8. 1. 1. 1. 1. 1. 0. 0. 0**

** ________ _____________**

**|____________**

**16. 1. 1. 1. 0. 1. 0. 1. 0**

** _____________ ____ ____**

** |__0_| |__0_| |__0___**

A digital signal has four levels. How many bits are needed per
level? Draw the digital signal assume the baud rate is 8 baud per
second.
Increasing the levels of a signal increases the probability of
an error occurring, in other words it reduces the reliability of
the system. Why and how can this be resolve?
What determines how successful a receiver will be in
interpreting an incoming signal?
Spectrum of a channel between 5 MHz and 4 MHz; SNRdB...

In long-distance digital phone transmissions, the information
travels in series (bit by bit) over the telephone network and is
clocked at the rate of a clock. When transmitting this information,
it can happen that long sequences of ’1’ are sent. Therefore, they
can show a DC component on the line (twisted pair, coaxial cable)
that may be filtered by the installation (presence of transformer).
To avoid such filtering, the natural binary code is transformed
into AMI (Alternate Mark Inversion) code....

Please code in Java and please implement constarints Digital
Root and Iterations Given a non-negative integer, print out its
digital root and the number of iterations required to reach it. The
digital root is the single digit number obtained by an iterative
process of finding the sum of digits. In the next iteration, the
sum of the digits in the previous iteration is computed, and the
process repeated until a single digit value is obtained. Input
Format The first line...

Sign extension means that any given signed number can be
represented with more bits by simply repeating the sign bit. For
example, 0005 = +5 and 00005 = +5. This holds true for negative
numbers as well. For example, 1011 = -5 and 11011 = -5. Also,
11111011 = -5. Using finite summation notation, prove that sign
extension can be applied to any 2's complement binary integer, B,
with b number of bits

Adder
Start out by picking 2 positive six bit binary numbers that are
less than 3210, written in 2's complement notation. The
eventual goal is to add these two numbers.
1) Look at the LSB bit of the numbers, and using logic gates
(NANDs, NORs, etc.) design a circuit that correctly gives the right
output for any possible combination of bits in the LSB place.
2) Now look at the next column to the left (next to LSB). In
this...
