If it's a modified square wave does that mean that there exists harmonics in the wave form, Fourier Harmonic transform ?Not really a good thing to learn though!
CRT technology is absolutely obsolete, and is being dumped at the scrapyards at a scary rate (go to your local dump and have a look at the TV mountains!).
All new TVs and new 'scopes are flatscreen LCD technology. If you really want something to leard then don't waste time with obsolete high voltage CRT technology, it was the last "vacuum tube" to bite the bullet, and it did last a while, but it is OVER now.
Learn things that will be useful in 10 or 20 years from now, not things that were useful 20 years ago!
We've been there----he looks it up,either doesn't read it,or can't understand it,& comes back here asking silly supplementary questions!!The deflection coils that move the dot for a CRT are inductive so to make the scan a linear ramp then the waveform voltage must be modified, a kind of trapezoid so that the current is a linear ramp.
Why don't YOU look it up in Google instead of ME??
Sometimes looking up subject on the Internet or books, if it's there it may take an disgusting long time, so I figure asking questions may shoten my pursuit.Also the way subjects are presented in electronics or electricity at times puzzle me. So I seach for a better interpretation.And sometime I might get an idea through a discussion that movtivate other insights into the discussed subject or others,in which prompt me to do more reseach through Internet, books or forums.I just don't wait for an answer.Since you brought to mine attention about the wave shape wasn't a sawtooth,(in which, I didn't recognize) put me on the search to find out why that was so.Electronic and electricity can be obsured or ambigous concepts.The deflection coils that move the dot for a CRT are inductive so to make the scan a linear ramp then the waveform voltage must be modified, a kind of trapezoid so that the current is a linear ramp.
