Behind Digital Signal Processing Technologies (DSP)

It is difficult to think about life without technology at these days, but is definitely part of our lives, allowing us to do so more quickly and easily. But, what is behind all the technological advances?

Most users of technology ignored entirely how technological devices work.

occasionally it's amusing to observe how two folks argue heatedly about the properties of a device, on one occasion I heard two young boys discussing the capabilities of a mobile phone equated to additional.



The first couple alleged that his cell phone has more memory and MP3 player. The second couple claimed that his phone had more features like voice command; even so both ignore the true functioning of both devices.

If we keep in mind the actual operation of an electronic device, we would note that actually the differences are only for marketing itself, when almost all electronic devices applies the same pedestal of operation.

Nowadays computer technology is the mother of all technologies, because our real search in new technologies is to find devices that perform certain tasks in an autonomous way.

perhaps there will be those who think different but it's matter of analyzing certain well-electronic devices.

for instance:

The MP3 player

The MP3 needs basic computational elements: memory, processor and program.

Digital Camera

The digital camera needs basic computational elements and other advanced elements.

The core of computer technology comes from the data processing. The computers have their own language of communication known as machine language. In the language machine electrical impulses are interpreted as binary (0, 1) states and each state is represented in binary numbers more complex that turn into more complicated elements.

The data processing is divided into the following categories:

Digital Signal Processing (DSP)

Interpretation of binary data

Interpretation or pattern recognition

Digital Signal Processing (DSP) is among the most used elements of the technology and among the most significant, if we take the example of the cell phone, it would have been most useful for both young explain which cell phone applies a processing algorithm more efficient than the other instead of compete which has more memory.

DSP is a set of algorithms that allow the processing of information from analog world that has been previously translated into a digital system easily understandable by a computer, you are able to filter noise environment, eliminate imperfections in photographs, interpret our voice commands among other functions.

The Interpretation of binary data corresponds to the processors because those are responsible for interpreting each command from a program. Each processor has its interpreting system known as instructions, where each data set represents a binary instruction; this is main the operation of computers.

Pattern Recognition is data processing element corresponding to a series of complex techniques (including DSP's). Most of these techniques lie with the technology of artificial intelligence: Neural networks.

A neural network is an emulation of the brain (biological neural system). The neural networks have the ability to carry out tasks that the classical linear processing data may not even like a neural network is implemented linear processing system but so emulated.

The neural network provides functions that some devices have like: voice recognition, face recognition among other people.

a lot of folks ignore what is behind everything on technology, but it's matter of thinking and gives some credit to those who are behind the technological advances because thanks to them our lives are comfier.
