Abstract

PURPOSE:To secure the modulation for the horizontal saw-tooth wave via the positive or negative horizontal pulse plus the right-ascending or right-descending vertical saw-tooth wave. CONSTITUTION:The left-half of the vertical saw-tooth wave is applied to the base of transistor Tr16, and the positive horizontal pulse is applied to the base of Tr20. Thus the peak value of the horizontal pulse is clamped by diode 22. If the peak value of the vertical saw-tooth wave is set under the prescribed level, Tr20 is cut off for the period when the horizontal pulse enters the base of Tr20. While the base potential of Tr20 lowers down for the period during which no horizontal pulse enters to secure the conducting state. In the right-half of the vertical saw-tooth wave, Tr20 functions as the reverse mode. Waveform c is obtained at the emitter of Tr16, and the collector output wave of Tr25 applied to the base of Tr25 via capacitor 23 and resistance 24 features like waveform d to be then compounded with saw-tooth wave 12. Thus waveform e is obtained.
