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
What is meant by ductile iron k14?
Metals are produced in the cooling mode, the signal (k) are specified.
What is the difference between audio generator and signal generator?
Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
What is meant by sampling in analog to digital conversion?
while conversion of analog signal to digital signal, we need to convert continuous analog signal to discrete signal. this can be done by dividing the analog signal into specific time slots. this process is known as sampling. there is a condition for sampling that can be given as follows. fs<=2fm
What are the advantages of FSK?
-> frequency shift keying promotes long distance communication. ->it has high security. ->low noise ->efficiency is high. ->decoding of signal is easy.
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 meant by coding and decoding using in arithmetic progression?
encoding is the process by which information from a source is converted into symbols to be communicated. Decoding is the reverse process, converting these code symbols back into information understandable by a receiver.
What is meant by base band digital signal?
It means the signal is not modulated.
What is meant by signal related to signals and systems?
signal is a physical quantity.the system which capable of analyzing the signal is the system.
What is decoding a video?
I think it has to do with video decoding..?
Can you split from standard video yellow to ypbpr?
A single cable carrying video will be carrying a composite video signal. This signal has brightness and two color signals encoded into a single signal. To generate a component signal (YPbPr)a video decoder is required. They are available from many sources from low cost domestic units to stunningly expensive broadcast models. The better the decoder, the better the resulting image. It is very important to understand that a composite signal has suffered losses because of the encoding. Decoding the signal to component does not restore that quality. Component interfaces can handle high definition as well as standard definition signals. Decoding a composite signal will result in a standard definition signal. Connecting it to a high definition input will not result in a high definition signal. Normally, the only reason to decode the signal to component is to interface to a device that only accepts component signals.
What is meant by amplifier?
An amplifier amplifies the small input signal to a high signal without changing its freqency.

What is the ISBN of Decoding Reality?
The ISBN of Decoding Reality is 0199237697.
When was Decoding Reality created?
Decoding Reality was created in 2010.
What is meant by signal?
A signal is defined as a the physical quantity that varies with time, space or any other indepenent variables.
Why as signal is usually grounded?
If meant ac signal then it is grounded so that the reference voltage is 0 & we get +ve voltage.
