i have got an assignment to give five examples on each digital and analog systems?
i got this assignment in my new digital computer logic class plz help me out plzzzzzzzzzzzzzzzz
All natural systems are analog systems..
Values can vary to any level… And are not limited to zero and one..
1. Human brains..
3. Voltage regulators for fans
4. Microwave ovens
5. Car and bike throttles
2. Digital tvs
3.on off switches
4. One way valve..
5. Digital cameras.
How do analog optical systems, digital optical computers and optical subsystems differ???
what is an example of each type as well
Analog means there are an infinite number of states between the highest and lowest. Digital means there are two states commonly referred to as high/low, on/off 1/0.
All computers these days are digital
Optical just means the signal is in the light spectrum instead of the electrical spectrum
In a nutshell please explain the difference between analog and digital communication systems?
A rather simplistic explination but here goes.
Analogue communications systems send a series of waves with varying amplitutde and frequency, the frequency determins what sound is sent and the amplitude determins how loud it is. Signal strength directly affects amplitude so if your signal is week things may get quiet.
Digital comunications breakseverything down into a series of 1′s and 0′s (binary) and sends these as a stream to be rearanged at the other end. Signal strength has no detrimental effect as long as all the 1′s and 0′s get through (as no matter how weak they are they are still recognisable as a 1 or 0) but interferance occors if any data is lost (i.e. When a 1 or 0 does not get through due to too weak signal).
