Digital is what concerns the fingers (the limbs of the hands and feet of the human being). The concept, however, is now closely linked to the technology and the computing to refer to the representation of information from binary mode (in two states).
The digital systems (like the computers ) use a logic of two states that are represented by two levels of electrical voltage: tall (high or H) and low (low or L). By way of abstraction, these states are replaced by ones and zeros, facilitating logical application and arithmetic.
This binary system composed of ones and zeros allows you to store, process and transmit any type of information. It is possible to talk about combinational digital systems (whose outputs depend on the status of the inputs at a given time) and sequential digital systems (the outputs are also affected by the previous states).
The digital signals , meanwhile, use discrete or discontinuous values, unlike analog signals (which appeal to a continuous series of values). When operating with limited values, the transmission of information is easier and more reliable.
Among the advantages of a digital signal (television, for example), are the possibility of amplification and reconstruction at the same time, the correction of errors in reception and infinite generation without loss of quality.
In the field of electronics , the digital circuits They work with information coded in only two states (ones and zeros, according to the different voltage levels).
Digital music
When you talk about music digital, it is possible to make two very different interpretations: first, it can be understood as a synonym for electronic music, since it is produced using instruments that do not rely on the principles of acoustics to emit their sounds, but rather generate them digitally; on the other, the concept can refer to digital distribution formats, both downloaded through virtual stores and those stored on CDs or DVDs.
Given the greater comfort offered by digitally distributed music, few people stop to think about the advantages of analogue media, such as disk vinyl. Formerly, the sound waves emitted during the recording of an album were produced producing physical marks on the surface of the disc, which ensured that each sound left a unique mark. This is supported by those who say that digital music does not seem natural, that it does not transmit the heat of the artists.
In addition, it is known that vinyl records collected all the sound spectrum emitted in the recording rooms, including those frequencies that are imperceptible to our ears. When a note is naturally issued, if the instrument It is well tuned and gets a proper projection, along with it sound many others, which are known by the name of harmonics; This increases the richness of an interpretation, and is something that cannot be seen on a CD in the same way as on an analogue medium.
Without a doubt, the sound embodied in a vinyl record is more natural than a recording made entirely with digital equipment, but this does not indicate that this last option does not offer clear advantages. For example, and perhaps the greatest of all, it does not deteriorate with use or with the passage of time; how much would the lovers of opera and music of the first half of the twentieth century give for having clean and stable recordings of their favorite singers.
Another of the strengths of digitally distributed music is that it can be played on a host of devices, of varying sizes and technologies, and that does not take place. Thanks to cloud storage services, in addition, local disk space is no longer a problem, since you can have a potentially unlimited number of songs stored in memory remote
