| Abstract: | The characteristic equation of the varied mid-voltage for "HITACHI"OTL vertical output circuit is introduced. The dissipated power and efficiency of the circuit are precisely calcalated. Due to the change of the parameters of "HITACHI" Circuit, the effi- ciency of the circuit increases by over 50 per cent. At the same time, the dissipated power of the horizontal driver and frequency channel selector system are reduced, too. The con- dition of the low dissipated power circuit is realized. The theoretical calculation agrees with the experiment result basically. |
