Analog signals are continuous signals that vary in amplitude and frequency in proportion to the information they carry. They are used to transmit information in a variety of applications, including audio, video, and telecommunications.
Analog signals are typically transmitted over a physical medium, such as a wire or a radio wave. The medium is modulated with the analog signal, which causes the medium to vary in some way. The variation in the medium is then detected by a receiver, which demodulates the signal to recover the original information.
There are a number of different ways to modulate a physical medium with an analog signal. One common method is amplitude modulation (AM). In AM, the amplitude of the carrier wave is varied in proportion to the amplitude of the analog signal. Another common method is frequency modulation (FM). In FM, the frequency of the carrier wave is varied in proportion to the frequency of the analog signal.
The choice of modulation method depends on the application. AM is simpler to implement than FM, but FM is more resistant to noise and interference.
Analog signals are still used in a variety of applications today, but they are gradually being replaced by digital signals. Digital signals are more efficient and reliable than analog signals, and they can be processed and transmitted more easily.
Here are some of the advantages of analog signals:
* They are simple to generate and process.
* They can be transmitted over a variety of physical media.
* They are relatively immune to noise and interference.
Here are some of the disadvantages of analog signals:
* They are not as efficient as digital signals.
* They can be distorted by noise and interference.
* They are difficult to process and store.

Analog transmission is a transmission method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. ... Others define that as digital transmission and as a digital signal.
