Analog vs Digital

From the technological point of view, analog and digital are two types of processes used for the transmission of any electrical signal. In general, the information that is transformed into an electrical signal is audio or video. This is done by translating any information into different types of electrical signals. For the analog format, the translation of the data is in electrical impulses, which vary in amplitude, while for the digital format, the translation of the data is in binary format with two different amplitudes that represent each bit.

The devices come with integrated ‘translation’ facilities, so it has equipment such as analog or digital telephones, fax machines, modems, watches, watches, etc. A microphone and a speaker are good examples for analog devices.

Analog technology is older and has been used for decades. It is also cheap, but the problem with analog signals is that there is a limitation in the size of the data that can be transmitted at any given time.

Digital technology has changed the way most of our equipment works. It changes all the data in binary code at the transmission point and this binary code is reassembled into data as originals at the point of reception of the transmission. Since digital signals can be manipulated by software, it offers more options than an analog one. In telecommunications, compared to analog signals, since digital signals have an original model that must be replicated at the transmission’s completion point, it is more precise and clear.

However, another difference between digital and analog technology is that of quality. Since digital devices are translating and reassembling data, the quality is not as good. But the advance in computer technology allows artificially eliminate possible errors and disturbances in any digital signal. Digital is still quite expensive compared to analog. However, global technology giants are working to reduce the price.

The most efficient use of digital technology has been made in the cell phone industry, with the analog that becomes redundant, although the sound quality is better in the latter. It can be said that all natural signals are analog. For example, when human speech is directly transformed into electrical signals, it is an analog signal. But converting it to digital format opens an infinite possibility of use, as a simple act of saving that in a computer.
