Frequency Measurementscan hardly be achieved by other means. (Except “Absolute frequency measurement with rotating pointer”, p. 360).

The Cathode Ray Tuben Fig. 2-1., the cathode cylinder having been removed for this purpose. As can be seen, it is bent double. This is done to obtain maximum heating by the most economical means. To insulate it from the cathode, the filament is coated with a layer of kaolin. The filament can be heated by direct or alternating current.作者: JEER 時(shí)間: 2025-3-24 05:00

Uses of Intensity ModulationIn most measurements with the oscilloscope, the electron beam, and thus the spot, is deflected by both pairs of deflection plates in co-ordinates at right angles to each other -the .- and the .-axes. It is, however, sometimes necessary to make a third quantity, namely time, visible on the fluorescent screen.作者: ordain 時(shí)間: 2025-3-25 02:08
