We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

640 RICHARDSON'S BLUEBOOK OF PROJECTION Scanning Impulses, page 645 14. What components generate the alternating currents applied to the deflecting vanes of a television cathode ray tube? 15. What is meant by interlaced scanning? 16. What is a saw tooth frequency and how can it be generated? 17. How is the scanning action of the cathode ray tube electron beam synchronized with the scanning action of the television camera's electron beam? 18. How many saw tooth oscillators are needed in a television receiver? 19. How are horizontal and vertical scanning impulses separated in the television receiver? 20. What precaution makes certain that the video signal will never interfere with the synchronizing action of the scanning impulses ? 21. What happens to the electron beam in the cathode ray tube during the period of "fly back"? Why? 22. Is there only one method of generating saw tooth impulses? Is there only one method of deflecting the cathode ray tube electron beam? Is there only one method of arranging the oscillator circuit of a superheterodyne receiver?
