Analog & Digital Signals

by Natalie Brown

Here are 3 examples of Digital & Analog Technology:


1.) Record player

2.) Cassette tape player

3.) Tube amplifier

These all represent Analog because they are all use signals or information to work.


1.) CD player

2.) DVD player

3.) Computer

These all represent Digital because they are seen as digits 0 and 1 also know as binary code.

Diffrences between Analog & Digital Signals

-Analog signals have waves that go up and down and have a trough and a crest.

-Digital signals are seen in binary code (0's & 1's) and are not curved but square/ rectangular waves making information travel through it faster

-Digital signals have better quality wave signals because the waves are square and the atoms can travel through them faster.

Diffrences between Analog and Digital technology

-Digital technology is read using binary code to create letters and words.

-Analog Technology is not digital. For example there is no analog technology when you can search the web with good quality pixels & signals.

-Analog technology works in waves to get signals.

Which is more preferred? Analog or Digital

Digital would probably be preferred over analog because they are newer. Plus people these days would prefer the more advances technology such as a compact disc over an old cassette tape. The sound quality is also not as scruffy which is why a lot of people changed from a cassette tape to a cd because its better. Digital is also more easier to use than an old cassette tape. Which makes more people want to have digital technology because it will save them the time of non-understandable old scruffy sounding cassette tapes.
