What are analog electronics?
Analog electronics are devices using systems working with a variable signal that works continuously. Small changes in the signal input cause minor changes in signal output. In principle, the electrical signal fluctuates both in the voltage and in the current, resulting in a proportional signal representing some original information. While technology is intuitive, it is inaccurate due to the ongoing nature of the signal. Analog electronics differ from digital electronics in that the digital method simply uses two information, one and zero to create a signal. For example, vinyl record is constantly reading a needle on a turntable until it is interrupted at the end of the record. An example of analog information would be to hold the pencil on a piece of paper and write a sentence without lifting. While this is expressed by Informatina Tom does not create a perfectly created writing sample. On the contrary, digital information can be represented by contact with a pencil and no contact, which gives a more accurate writing sample.
Analog electronics mediates information that is basically a simulation coded and transmitted by electric means. Some physical form is converted to information by a converter, a device designed to transmit one type of energy to another. This may include sound, light, pressure or any other form of phenomenon. One of the known examples of the converter is the microphone that is used to transmit sound to the electrical signal.
The signals for analog electronics are presented with the range of range. In principle, each signal is divided into different voltage and current levels that alternate to represent the information. This varies depending on the electronic device. For example, a pineapple stereo system could use seven volts to represent a specific frequency from the speakers, while 7.1 would be a step up from this frequency. In this way, the simulation of the song is finally introduced.

The amplitude modulation (AM) modifies the course of sinus voltage, while frequency modulation (FM) changes frequency. As a result, both AM, a change in the shape of the course and FM, the change in wave speed, work with separate analog devices, although they are often placed in the same electronic unit.
One disadvantage of analog electronics is what is called noise . During the variation of the analog signal, there are inevitably certain faults that lead to distortion or changes in the way of interpretation of the signal. This happens most often in electronics from thermal vibration particles at the atomic level. In situations in which the information is copied, this noise prevails with every generation.
