Is the cyclic redundancy check better than hamming code?
It depends on what you are doing. The cyclic redundancy check will only detect an error, while the hamming code can also correct many types of errors. However to perform this correction the extra error detection parity bits required in hamming code are many more than the bits needed for cyclic redundancy check, per data byte being checked. Normally cyclic redundancy check is done on large block of data that can be resent or retried to get the correct block of data (e.g. telecommunication channels, disk sectors). Normally hamming code is done on individual bytes or words of computer memory.
What are the advantages of using digital signals and why?
* Digital signals suffer less interferences than analogue signals. This means that when you listen to a digital signal you won't hear a hissing sound, as within digital signals regenerator circuits are used to clean "noisy" pulses. * Digital signals can be made very short so more pulses can be carried around each second, which means more information can be passed on.
What are the subjects in the electronics and communication?
signal and system,digital logic design , engineering maths,
What are analog and digital modes of operation of an instrument?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
Is baseband digital or analog?
Both, Like any other form of communication. However, all analog forms of communication/transmission will end in February of 2009. All manufactures have already changed to the digital format, therefore in a couple of months any older system will be obsolete.
How hamming codes works?
Hamming code is a linear error-correcting code named after its inventor, Richard Hamming. Hamming codes can detect and correct single-bit errors, and can detect (but not correct) double-bit errors. In other words, the Hamming distance between the transmitted and received code-words must be zero or one for reliable communication.
Write the generator matrix for the hamming code 51?
i want hamming code matrix (h and g)
Construct a 12-bit Hamming code for the characters A and 3 ASCII. 3 equals 00110011?
Hamming Code for A: 010010000100 (The strike numbers are the check bits) Hamming Code for 3: 001100011101
How can hamming code be used to correct burst errors?
Hamming code is only used for single bit error :/
What is haming code?
In computer organisation ...what is hamming code.?
The code 11110101101 was received Using Hamming encoding method 2 what is the original code sent?
the code 11110101101 was received using hamming encoding algorithm what was the original code sent
In hamming code you have 4 bit data How many extra bits are required for code?
you need thee extra bit for 4 bit data in hamming code.
How do i construct a Hamming code for 10011101?
Go to school!
Calculate hamming code between 1000110 and 1110100?
hamming code between 1000110 and 1110100 can be calculated by just exoring both codes with each other as follow: 1000110 1110100 ------------ 0110010 now by counting the ones in the result that gives 3 then hamming dictance = 3
What are the limitations of Hamming Code?
Hamming code handles only single-bit errors-two or more errors will cause an incorrect syndrome value. It can detect double bit error but not corrected
Why digital communication is known as digital communication?
because it's digital communication.
Whai is the difference between CRC and hamming code?
In CRC, the redundant bits are derived from binary division to the data unit. While in hamming code, the redundant bits are a function of length of the data bits.
