Advantages of Digital Systems
Ease of programmability. The digital systems can be used for different applications by simply changing the program without additional changes in hardware.
Reduction in cost of hardware.
Design is easy.
Result can be reproduced easily.
What is the difference between analog and digital signals?
Viewed from afar, the wave function below may seem smooth and analog, but when you look closely there are tiny discrete steps as the signal tries to approximate values: That’s the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.
What is the difference between analog and digital technology?
In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape. In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device.
