Is analog better than digital?
Analog signals are easier to process. Analog signals best suited for audio and video transmission. Analog signals are much higher density, and can present more refined information. Analog signals use less bandwidth than digital signals.
What are examples of analog and digital?
Examples of analog signals are Human voice, Thermometer, Analog phones etc. Examples of digital signals are Computers, Digital Phones, Digital pens, etc.
Is wifi analog or digital?
Traditional AM/FM radio and TV broadcasts communicate information through analog, or continuous, signals. Wi-Fi communicates information digitally, as discrete values – the 0's and 1's of binary data. This lets mobile devices easily send a wide range of data types, including video, image, speech and text.
