6-32. What digital computer section ofthe HUD set signal data processordistributes the clock pulses?1. Control logic2. Sequence control3. Symbol generator4. Processor counter6-33. The symbol generator operates inthree major modes. Each mode isdependent on the other, and all arecompleted simultaneously.1. True2. False6-34. During the sixth and seventhoperations of the line mode, whataction occurs with respect to the Xand Y data?1. X data is shifted2. Y data is shifted3. The X and Y channel rateregisters are shifted by thesymbol generator4. The BITE circuits check alldata in the X and Y channelrate registers for correctness6-35. The symbol generator samples theHUD busy signal for what reason?1. To decode information2. To generate a self-test mode3. To transfer data to the HUDimmediately4. To transfer data to the HUDwhen it is ready6-36. When the circle mode of operationin the symbol generator is beingused, the circle is drawn (a) inwhat direction and (b) begins atwhat point on the CRT?1. (a) Clockwise (b) top2. (a) Clockwise (b) bottom3. (a) Counterclockwise (b) top4. (a) Counterclockwise (b) bottom6-37. What is the purpose of thebright-up pulse delay in the circlemode of the signal generator?1. To compensate for the slowresponse time of the deflectioncircuits in the HUD2. To compensate for the fastresponse time of the deflectioncircuits in the HUD3. To turn off the symbolgenerator4. To turn on the signal generator6-38. What voltage is applied to the CRTanode of the HUD?1. 5,000 volts2. 10,000 volts3. 15,000 volts4. 20,000 volts6-39. The electrical power used for theoperation of the standby reticle ofthe HUD is obtained from whatsource?1. The high-voltage power supply2. The low-voltage power supply3. Outside of the HUD4. The HUD battery6-40. In the optical module of the HUD,what is the purpose of theautobrilliance sensor?1. To detect ambient light changes2. To adjust output voltage levelto the sensor3. To amplify manual brightnessinput signals from the controlpanel4. To detect ambient light changesand amplify output voltagelevel to the sensor6-41. At what rate are the symbols drawnon the CRT of the HUD video module?1. 15 times per second2. 25 times per second3. 50 times per second4. 100 times per second41
