ANALOG_ BUILDING
Analog builds a model, the model will not exactly match the original, but the quality can be quite good. Building duplicates of the duplicate will increase the error.
DIGITAL_ BUILDING
The error happens once. Every duplicate of duplicate has the same quality. The error is exactly defined ( max half square). The error depends on the grid’s density.
Depiction of analog signal
Depiction of digital signal
| Analog | Digital |
|---|---|
| The input is transmitted as a continuous signal that represents the course of the input signal. | |
| The quality is not defined. Every copy adds an error and reduces the quality. | The input is transmitted as a noncontinuous signal. The quality is defined. |
| Every copy of the copy has the same quality. |
The pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light is called voltage. (voltage = pressure)
SI unit - Volt
A flow of charged particles, such as electrons or ions, moving through an electrical conductor or space is called current
SI unit - Ampere
The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. (G=conductance)
R = V/I ; G = I/V = 1/R
