It is the opinion of historians that in order to better understand the present, you need to know the past. Searching for one's roots in this world is big business. Online family tree type websites are used by thousands of people to research their family histories, and some services don't come cheap. You can even pay someone to dig into your past to assimilate all available information and put it in a bound, printed volume. Here on RF Cafe, I research and post a lot of our profession's past. While the individual topics themselves might not bear significantly on the present, having an insight into the people's mindsets and progression of technology is - or should be - motivating. No, most modern televisions do not process analog signals, use a CRT, have vertical and horizontal hold adjustments, but then not too far in the future most televisions won't be much like they are now. Engineers and technicians of today's world have a distinct advantage over prior years' innovators because with enough ingenuity and fortitude, just about anyone can successfully bring a useful idea to market.

How Television Got Its Electronic "Eyes"

 - RF CafeAs revolutionary as airplanes without propellers - that's how much electronic television differs from the earlier mechanical television!

Whirling discs and motors required for mechanical television were not desirable for home receivers. Pictures blurred and flickered.

But now, thanks to RCA research, you will enjoy all-electronic television, free from mechanical restrictions - "movie-clear" television with the same simplicity of operation as your radio receiver.

Such "let's make it better" research goes into everything produced by RCA.

At RCA Laboratories, world-famous scientists and engineers are constantly seeking new and better ways of harnessing the unbelievable forces of nature ... for mankind's greater benefit.

Electronic television is but one example of the great forward strides made possible by RCA research - opening the way for who knows what new miracles?

When you buy an RCA radio or phonograph or television set or any RCA product, you get a great satisfaction ... enjoy a unique pride of ownership in knowing that you possess the finest instrument of its kind that science has yet achieved.

Dr. V. K. Zworykin, Associate Research Director and E. W. Engstrom, Director of Research at RCA Laboratories, examining the Iconoscope or television "eye" - developed in RCA Laboratories for the all-electronic television system you'll enjoy tomorrow.

About RF Cafe

Kirt Blattenberger - RF Cafe WebmasterCopyright

Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
