Differences in Analog Signals and Digital Signals 

Differences in Analog Signals and Digital Signals – Analog signals and digital signals are part of data communication. And data communication is part of a computer network. Before explaining the differences between analog signals and digital signals, on this occasion the author will discuss first about data communication.

Data communication

Data communication is the process of transferring data / information or the process of moving from one computer to another on a network, both on a small scale and globally

Data Communication Objectives

Data communication aims to accelerate and efficiency in the process of sending or receiving data, processing instalikes data remotely, speeding up the process of disseminating information, and using hardware remotely

Analog signal

A signal is a signal to continue or continue an activity. Usually this signal is in the form of signs, lights, sounds, etc. In a train, for example, a signal means a sign to continue or continue the journey to the next place / station, and usually this signal is sent by the relevant station.

Analog signals work by transmitting sound and images in continuous wave form (continuous varying). The two most important parameters / characteristics possessed by analog signals are amplitude and frequency.

Waves in analog signals that are generally in the form of sine waves have three basic variables, namely amplitude, frequency and phase. Amplitude is a measure of the high and low voltage of an analog signal. Frequency is the number of waves of analog signals in seconds. Phase is the angle of the analog signal at a certain time.

The following is an image of an analog signal.

Digital Signals

Digital signals are data signals in the form of pulses that can experience sudden changes and have magnitudes of 0 and 1.

Here is a picture of a digital signal.

Thus information about the difference between analog signals and digital signals. In principle, the difference between analog signals and digital signals is that analog signals are in the form of continuous waves, while digital signals are in the form of pulses 0 and 1.
