The vector representation of a convolutional code is g1=[1 1] and g2=[1 0]. If the received sequence is 11 11 01 10, we can use Viterbi Algorithm to decode it. The full trellis diagram, including the updated trellis state metrics, is shown below:
Time t1:
State 0 (00): Metric = 0
State 1 (10): Metric = 0
Time t2:
State 0 (00): Metric = 0 + (1-1)^2 + (1-1)^2 = 0
State 1 (10): Metric = 0 + (1-1)^2 + (1-0)^2 = 1
Time t3:
State 0 (00): Metric = 0 + (1-1)^2 + (1-1)^2 = 0
State 1 (10): Metric = 1 + (1-1)^2 + (1-0)^2 = 2
State 0 (01): Metric = 0 + (1-1)^2 + (0-1)^2 = 1
State 1 (11): Metric = 0 + (1-1)^2 + (0-0)^2 = 0
Time t4:
State 0 (00): Metric = 0 + (1-1)^2 + (1-1)^2 = 0
State 1 (10): Metric = 2 + (1-1)^2 + (1-0)^2 = 3
State 0 (01): Metric = 1 + (1-1)^2 + (0-1)^2 = 2
State 1 (11): Metric = 0 + (1-1)^2 + (0-0)^2 = 0
Therefore, the decoded sequence is 11 11 01 10.

A squelch circuit turns off the audio input to the speaker when there is no radio signal being received. This stops the speaker from producing annoying noise when no radio signal is being received.
It can be used as memory, it remembers the input of for instance A if the other input is 0. For example:A0XOR000101It is used to check the parity of received bits, in other words to checks the correctness of the data received (See Hamming fault correction) and can find and correct faults in a byte if there is only one fault.It can also be used as a bit-flipper if one input is A and the other is 1. For example:A1XOR011110
An active satellite acts as a REPEATER; it amplifies signals received and then retransmits them back to earth. This increases signal strength at the receiving terminal to a higher level than would be available from a passive satellite. A passive satellite only reflects received radio signals back to earth. fr0m: ZIA UR REHMAN D-05-ES-29 DCET Karachi Pakistan.
To avoiding the noise signal effect.Because the modulation is a technic which providing a high characteristic to transmitting the signal on long or short distance.Because the modulated signal received as high bandwidth,high performance of received signal and the modulation Technic is provide a less hight of antenna in wireless transmission which is expressed in the term :(hight of antenna=λ/4).

In recent years, the addition of systematic redundancy to the transmitted information in the form of error-control coding has proved to be a potential way to overcome channel disturbances that produce errors, in digital communication systems. However, with the evolution of error-control codes such as the convolutional codes, the complexity of the corresponding decoders has also been increasing. The function of such a decoder is to find a codeword that most closely resembles the received input sequence. The Viterbi algorithm (VA), which is one of the most extensively employed decoding algorithms, works well for codes with short constraint length K. But its memory requirement and number of computations poses a big obstacle when decoding codes with larger constraint lengths. In order to overcome this problem the concept of adaptive Viterbi decoding algorithm (AVA) was developed . In this project a modified Adaptive Viterbi Algorithm has been designed. As in the Adaptive Viterbi algorithm , the modified algorithm also does not examine all possible states of the trellis levels, thus reducing the memory, computational, and power requirements.

The goal of proportional representation is to ensure that the distribution of seats in a legislative body reflects the proportion of votes received by each political party or group. This system aims to provide fair and accurate representation for all voters and to promote a diverse range of perspectives in government.
A mental representation of a sensory experience is called a perception. It is the way our brain interprets and processes information received through our senses to make sense of the world around us.
one vote per state
The deputies of the Reichstag, the German parliament during the Weimar Republic, were elected by the German populace through a system of proportional representation. This meant that parties received seats in the Reichstag in proportion to the number of votes they received in elections. The elections were held every four years, and all adult citizens had the right to vote. This system aimed to ensure a diverse representation of political views in the legislature.
TCP doesn't immediately acknowledge every single received TCP segment. If a single segment is received it is necessary to wait for 100-200ms on the assumption that the receiving application will probably generate a response of some kind. But if there is delay in sending acknowledgement by the receiver then the network is delayed.
Equal representation means each region or state is represented by the same number of elected representatives. Proportional representation, on the other hand, means that the number of seats won by a party is proportionate to the received number of votes.
A proportional representation system is an electoral system designed to allocate seats in a legislature in a way that reflects the overall vote share of each party or group. Two common methods for securing proportional representation are the List System, where parties present a list of candidates and seats are filled based on the proportion of votes received, and the Single Transferable Vote (STV), which allows voters to rank candidates and ensures that votes are redistributed to achieve proportionality. These methods aim to provide a more equitable representation of diverse political views in the legislative body.
Proportional representation is an electoral system in which the distribution of seats corresponds closely with the proportion of votes received by each political party or candidate. It aims to ensure that all groups in society are represented in the legislative body in proportion to their level of support among the electorate.
