Elimination of black and white TV spots and bright lines appeared Analysis and Improvement
4 (Ⅱ) spoke out noise pulses 【【i was cutting the frame diagram bj hidden pulse TV Qing 1989 1 Hu ■ =. Jj Table 1 of the original project or two! Strong respect for the ink spots J point voltage sin love hearing black spot appears on the screen like (... (jcm) 1.5jj .----..., I {. J Fig 5fs) scan is way shorten the time At (h) of white against the process for too long lras H ・ At ten measures current frame sweeping weeping form 5 (b). This is causing some 80s top of the screen about the reasons for flyback lines. 4, the improvements can be seen from the 3 @ waveform is a sawtooth linear transition curve better. The mathematical formulation of the formula j: u = L_u} ten RLiLK + RLKT Figure 6, Table 2, after the change before the change point pulse @} f ⑨ red wave with a different point of spine / - range of different house so Oki line J to the total deflection Bin, does not produce the amount of one hundred (V ...) (linear sound) than the same symptoms U7r no i l TV dance rlV of 1989 where i: K i, slope changes, T for the field scanning period, it is easy to know K and time T is directly proportional relationship, this wave is the wave we need. It is conducive to the diode cut blanking, and cutting level are not subject to the restrictions ⑩ point bias, the other,[link widoczny dla zalogowanych], hidden diode ⑨ access point, the linear circuit (deflection coil) have a certain place. Linear circuit is not easy to cause parasitic oscillations. Taken by the conical cap blanking pulse in ⑨ point (see Figure 7) can be completed elimination of the two kinds of base failure. Figure 7 @ frame blanking signal from the original point of change at the point now ⑨ circuits such as the 7 shows changes in the blanking of the cathode diode in series 4R35/2700T 2AP9 What the Buck with m from the limit. If dR35 too large (when taking 1.5k mortar), as the place to join the emitter frame blanking pulse amplitude is too small, an inverse scan process Du frame as the release of the CD just can not make, over less than a frame blanking effect, be healthy top of the screen appears bright line flyback. If the 4R35 is too small (taking 510 hours) as the place to join the emitter frame blanking pulse amplitude is too large, the frame is scanned as the process will also put on top of the screen to see the next cut-off caused by light. Therefore, in order to make the frame blanking blanking signal a real role to play,[link widoczny dla zalogowanych], dR35 2700 to take good heap, 4R35 of resistance is the result of the workshop I obtained several production tests, bend workshop for mass production. 5. Improved analysis of the effect of these changes according to good effect. Even if the mining stomach deflection coils from different manufacturers, no two kinds of failure phenomenon 【state and each TV can also save the two components, Puma costs down and improve the production quality of One Man Table 2 Comparison of before and after a more political The results for reference. NV-M5EN integrated camera recorder's sound changing frequency Chishui County Radio and Television Bureau Peng Hanlin NV-MSEN integration of compact cameras. Operating cylinder stupid, especially suitable for use with the news coverage. Kay by indiscriminately shooting Iraqi splash sound carrier frequency modulated with the amount of TV system PAL ~ D are different. This tie down, to make the aircraft the same ten-frequency output can be. Home TV set with table use. The system must be thick aircraft radio audio device to set the amount of 6.5MHz. NV-M5EN integrated video camera for video and audio output are attached to common video recorders, video with its past output is connected via 14-pin socket and shed by random attachment adapter power output. The adapter model Vw ~ AM5. Its main functions are: Vice output through the standard jack points l the video and audio signals for transcription or monitor use; through the RF output jack output meter VHF band frequency communication No. 3 or 4 (with a channel switch), for the general power Rb images and sound machine weight was; DC power supply required for video camera; can be individually used as a charger for the camcorder's battery charge. As multi-function, small size, its internal structure is very compact and open when the adapter housing to change decadent, to find the RF modulator box and its model for the NEC for a 17701,[link widoczny dla zalogowanych], printed on the side of small box, small box of the two roller covers can be easily shielded open, the use of a lot of micro RC lead-free components, so the whole volume even smaller than the average matchbox. Radio frequency integrated circuits for the transformation of the post just TA767, pieces of MG amount of its l women T757, relentless l received on the LC resonant circuit of the decision, see Gang. Loop as long as the change in capacitance or inductance loop,[link widoczny dla zalogowanych], indigo can be changed back to the foot of the resonant frequency,[link widoczny dla zalogowanych], that is changing the sound contained snail. First find the inductance L, the shape and used a small radio in the same week, but much smaller off-plot, model 502V7224. Therefore, as stressed by the core test, we found that the adjustment range is small, does not meet the requirements, so the government by adjusting the loop capacitor C hope approach. Yung C bus ride back was a swaddling clothes small tubular capacitors, inductors L attached to the bottom of the groove-like seat, you can use television technology in 1989 for a 1 photo
