About the analog TV and digital TV, we
found the differences are as follows:
Digital TVs are beginning to gain
widespread acceptance all over the world while analog TVs are slowly
disappearing. The primary difference between these two types is with the
signals that they can process. Analog TVs are restricted to analog signals while
Digital TVs can process digital signals and analog signals.
Since analog TVs can only process analog
signals, it is also quite prone to the problems that analog signals experience.
Problems like noise, interference, and even distorted displays are very common
in analog TVs. Though digital TVs can still be affected by these problems if
the signal is also analog, switching to a digital signal almost eliminate it.

Analog TV sets use cathode ray tubes as
their display while digital TV sets use flat panel display like LCD, plasma, or
LED. Consequently, analog TV sets are big and bulky compared to digital TV
sets. Analog TVs also consume a lot more power compared to digital TVs.
Digital TV sets can be in 480p or more
commonly known as SD or even in 780p or 1080i/p which is known as HD or high
definition. HD makes it possible to increase the size of the TV sets without
compromising the quality of the image on screen. Analog TV sets use the
standard definition. Though there have been attempts to implement HDTV analog
sets at first, the requirements in terms of bandwidth were just too great for
it to be feasible.
Analog TVs are usually limited to sizes
of below 30 inches because creating much larger screens pose greater challenges
without any real gains in the image quality. Digital TVs have been growing
since they were made and screen sizes of over 50 inches are now quite common.
There are still some benefits that you
can get with analog TVs that are mostly due to its use of CRT. Analog screens
have a very fast response time making it excel in showing fast motion videos.
Analog TVs also have better contrast compared to most digital TVs. There might
still be advantages for analog TVs, but developments in technology have begun
to improve on the shortcomings of digital TVs.
Summary:
1. Analog TVs can only accept analog signals while Digital TVs can accept both digital and analog signals
2. Analog TVs are prone to noise and distortion while Digital TVs are not
3. Analog TVs are usually made with CRT displays while Digital TVs use flat panel displays
4. Digital TVs can be in HD while analog TVs can only be in SD
5. Analog TVs are restricted to under 30 inches while Digital TVs above 50 inches are already common
6. Analog TVs have advantages over digital TVs that are largely related to the CRT
