Analog VS Digital
By: Andrew Sackella
Examples of Analog Technology
Analog Clock- An analog clock is an example of analog technology because it first has to be wound up to maintain the correct time, but then it record those movements and be able to display the time.
Record- This is an example of analog technology the disc player has to read then record the sound, in order to play it back later.
Examples of Digital Technology
Computer (Monitor)- A monitor is an example of digital technology because it displays information, written in binary code. It works by receiving binary code then changing the code from 1s and 0s to a high definition image.
TV- A television is the last example of a digital device. A TV is classified as a digital technology because it receives the binary code which is transmitted via a cable box or satellite and turns the code into a display which we watch.
Analog Signals VS Digital Signals
Analog signals are a continuous signal.
Analog signal look like sine waves, curvy in form.
An analog signal replicates the original sound wave.
Discontinous signals generated by a computer chip
Uses binary code to transmit information.
Once it recivies the signal, it interrupts the binary code, then plays a new sound which sounds like the original.
Analog Technology VS Digital Technology
Analog records the records the original waveform then transmits it for use.
Analog Technology will degrade over time.
Stored in the form of a wave signal.
Digital Technology takes samples and turns them into numbers which are then used in the device or technology.
Doesn't degrade over a period of time.
Sorted in the form of a binary bit.
Digital devices are devices that have a starting and stopping signal/wave.
