List three existing inventions or technologies that played major roles in the development of television. Briefly explain how each of your choices was fundamental to the invention of traditional or flat-screen televisions.

The three existing inventions or technologies that played major roles in the development of the television are;

1. Facsimile system

2. The cathode ray tube

3. The scanning disk

Explanation:

1. Facsimile System

The transmission of images and text of scanned document through a telephone line to be received at a telephone to which is connected a fax machine or similar output devices.

The sending fax machine converts the image of the object to be sent into audio frequency tones which the receiving fax machine converts back into an image which is then printed

The first Electric Printing Telegraph was invented by Alexander Bain

The wireless transoceanic radio facsimile was invented by Richard H. Ranger.

The invention proved the possibility of the transmission of information through wired or wireless communication to an audience

2. The Cathode Ray Tube

The cathode ray tube consists of consisted of a fluorescent screen which emitted visible light that could be codded as images when impacted upon by a beam of electrons

The inventor of the cathode ray tube was Karl Ferdinand Braun in 1979

The invention was the forerunner of the idea of the present day television set

3. The Scanning Disk

The scanning or Nipkow disk is a metal disc consisting of a series of holes arranged such that a projected image on the disk surface is traversed by the arc described by the hole of the rotated in a way that each arc of each hole is adjacent to the arc of the hole before it

The transmitted light is sensed as an light intensity that is synchronous to the output voltage representative of the picture as video lines.

The invention is the bases of a televised motion picture
