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

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).
Is quantize one of the stages occurring in the process of analog digital conversion?
Yes. The stages are Sampling, Quantizing and Encoding (in that order)
Can you Compare and contrast analog and digital forecasting?
Digital forecasters rely on numerical data Analog forecasters involves comparing weather patterns to patterns that took place in the past
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 is OFDM training symbol?
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.
What are the digital encoding schemes?
converting digital data to digital signal.

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
What is encoding in digital communication?
See SSH and SSL is the way in which information is percieved and processed.
Is a Vistaquest digital camera better than a Coolpic digital camera?
Comparing digital cameras all depends on what you are looking for in a camera. Try comparing the megapixels on the camera. The higher the megapixel, the better the picture it will produce.
Applications of number system?
Number systems used mainly in encoding, cryptography, digital computing.
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
Is quantize one of the stages occurring in the process of analog digital conversion?
Yes. The stages are Sampling, Quantizing and Encoding (in that order)
Is LPCM lossless audio?
LPCM, also known as linear pulse-code modulation, is a method that is used for encoding audio information in digital form. It is commonly used for lossless encoding in a compct disc using the Red Book standard.
What is the difference between ASTC and NSTC digital tv reception?
NSTC is the old analog system of encoding over-the-air television used in the US. ASTC is the new digital system for over-the-air television.
What are the capabilities of digital communication systems?
A digital communication system consists of six basic blocks. The functional blocks at the transmitter are responsible for processing the input message, encoding, modulating, and transmitting over the communication channel.
