What is the digital to digital signal encoding technique?
The digital encoding techniques are of two types--Polar and Bipolar. The polar encoding are--RZ(Return to Zero), NRZ (No RZ) , Manchester and Differential Manchester. Bipolar encoding are--AMI ( Alternate Mark Inversion) and BnZS ( Bipolar n Zero Substitution).
Why do you need to encode a signal?
Encoding converts data in one format to another format. This is important in computer technolgoy, communications engineering, control engineering and signal processing.Encoding is typically done to utilise one or more of the following advantages:Compression of data for more efficient data transfers or storage.Improve the quality of a transmission signal - digital encoding is often used to recude the effect of noise and signal attenuation.Remove unneeded information relative to the application (digital TV signals consider the quality of human vision and encode the signal accordingly - animals who can see at higher rates than us, such as birds, would be very unimpressed with what they see on the TV!)Convert data into a format to communicate with attached peripherals.Encrypt data for security reasons.There are certain to be other uses, since the methods of encoding are so varied, but this should give you an idea of why it is an important process.
What are the purposes of signal processing?
With DSP you can change, modify, study the properties of signals more easily than analog signal processing. You can do modulation, encryption, decryption, encoding, decoding, multiplexing, comparing etc

Important factors that can be used to comparing the various digital-to digital encoding schemes?
A lack of high-frequency components means that less bandwidth is required for transmission. In addition, lack of a direct-current (dc) component means that ac coupling via transformer is possible. The magnitude of the effects of signal distortion and interference depend on the spectral properties of the transmitted signal. Clocking: Encoding can be used to synchronize the transmitter and receiver. Error detection: It is useful to have some error detection capability built into the physical signaling encoding scheme. Signal interference and noise immunity: Certain codes exhibit superior performance in the presence of noise. Cost and complexity: The higher the signaling rate to achieve a given data rate, the greater the cost. Some codes require a signaling rate that is in fact greater than the actual data rate
Definition of digital signal encoding?
encoding means conversion of data into bit strem..
What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Which layer of the OSI reference model is responsible for signal encoding?
Physical layer which is the first layer in OSI reference model is responsible for signal encoding and decoding.

What is a method of translating data into code?
One method of translating data into code is by using encoding techniques. Encoding is the process of transforming data into a format that can be easily processed or transmitted by a computer. Common encoding methods include binary encoding, ASCII encoding, and Unicode encoding. These methods assign numeric values or patterns to represent the data, allowing it to be stored or transmitted as code.
What are the digital encoding schemes?
converting digital data to digital signal.
What is delay modulation in binary encoding?
In telecommunications, delay encoding is the encoding of binary data to form a two-level signal where (a) a "0" causes no change of signal level unless it is followed by another "0" in which case a transition to the other level takes place at the end of the first bit period; and (b) a "1" causes a transition from one level to the other in the middle of the bit period.Delay encoding is used primarily for encoding radio signals because the frequency spectrum of the encoded signal contains less low-frequency energy than a conventional non-return-to-zero (NRZ) signal and less high-frequency energy than a biphase signal.Delay encoding is an encoding using only half the bandwidth for biphase encoding but features all the advantages of biphase encoding: To be rewritten: It is guaranteed to have transitions every other bit, meaning that decoding systems can adjust their clock/DC threshold continuously. One drawback is human readability (e.g. on an oscilloscope)
What is the difference between encoding and modulation?
Encoding: The way in which the computer data is represented is known as encoding, there are several encoding techniques (Unipolar, Bipolar and Biphase).Modulation: Modulation is the method of changing some of the characteristics of the message signal so that it can be transmitted to comparatively large distance without(least) getting affected by noise or unwanted signals.Encoding: The way in which the computer data is represented is known as encoding, there are several encoding techniques (Unipolar, Bipolar and Biphase).Modulation: Modulation is the method of changing some of the characteristics of the message signal so that it can be transmitted to comparatively large distance without(least) getting affected by noise or unwanted signalsEncoding : Digital or Analog data --> Digital signalmodulation : Digital or Analog data --> Analog signal

What do you mean by Duo binary encoding?
Duo binary encoding is nothing but any information either that continuous or discreate signal it will encoded in to binary in the form of set of two binary numbers. It is called as duo binary encoading
