Rev 2.02 E6D02 Cathode ray tube (CRT) persistence refers to the length of time the image remains on the phosphor screen after the beam is turned off. E6D03 If a cathode ray tube (CRT) is designed to operate with an anode voltage of 25,000 volts, and the anode voltage is increased to 35,000 volts the image size will decrease. E6D04 Exceeding the anode voltage design rating can cause a cathode ray tube (CRT) to generate X-rays. E6D05 A charge-coupled device (CCD) samples an analog signal and passes it in stages from the input to the output. E6D06 A charge-coupled device (CCD) in a modern video camera stores photo-generated charges as signals corresponding to pixels. E6D07 A liquid-crystal display (LCD) is a display that uses a crystalline liquid to change the way light is refracted. E6D08 Core permeability (for a given size core) is the property that determines the inductance of a toroidal inductor with a 10-turn winding. E6D09 The usable frequency range of inductors that use toroidal cores, assuming a correct selection of core material for the frequency being used is from less than 20 Hz to approximately 300 MHz. E6D10 One important reason for using powdered-iron toroids rather than ferrite toroids in an inductor is that powdered-iron toroids generally have better temperature stability. Applications for powdered Iron toroids would be oscillator and filter circuits where inductance stability with temperature is important. . E6D11 Ferrite beads are commonly used as VHF and UHF parasitic suppressors at the input and output terminals of transistorized HF amplifiers. E6D12 A primary advantage of using a toroidal core instead of a solenoidal core in an inductor is that toroidal cores contain most of the magnetic field within the core material. E6D13 Forty three turns of wire will be required to produce a 1-mH inductor using a ferrite toroidal core that has an inductance index (AL) value of 523 millihenrys/1000 turns. N turns = 1000 x (√ (L / AL)) or N turns = 1000 x (√ (1 / 523)) or 43.7 turns Jack Tiley <strong>AD7FO</strong> Page 59 3/15/2009
