Analog and Digital Signal
What is Signal?
In networking, signals are typically digital in nature, consisting of binary data that is encoded into electrical or optical signals. These signals are then transmitted through the network and decoded by the receiving device to extract the original data.
The quality and strength of signals can be affected by various factors such as distance, interference, and noise, which can impact the reliability and speed of network communication.
What is an Analog Signal?
Analog signal is a continuous signal in which one time-varying quantity represents another time-based variable. These kind of signals works with physical values and natural phenomena such as earthquake, frequency, volcano, speed of wind, weight, lighting, etc.
What is a Digital Signal?
A digital signal is a signal that is used to represent data as a sequence of separate values at any point in time. It can only take on one of a fixed number of values. This type of signal represents a real number within a constant range of values. Now, let’s learn some key difference between Digital and Analog signals.
Characteristics ofAnalog Signal
- These type of electronic signals are time-varying
- Minimum and maximum values which is either positive or negative.
- It can be either periodic or non-periodic.
- Analog Signal works on continuous data.
- The accuracy of the analog signal is not high when compared to the digital signal.
- It helps you to measure natural or physical values.
- Analog signal output form is like Curve, Line, or Graph, so it may not be meaningful to all.
Characteristics of Digital Signals
- Digital signals are time separated signals.
- This type of electronic l signals can be processed and transmitted better compared to analog signal.
- Digital signals are versatile, so it is widely used.
- The accuracy of the digital signal is better than that of the analog signal.
