摘要:
The video amplifier circuit comprises a complementary symmetrical arrangement of a first and second solid state transistor element with the video input source coupled through a level shifting circuit to the first element and through a DC level shifting circuit to the second element and with means provided for operating each element in a clamped mode approaching saturation. Additional circuit modifications include means for modulating the video input signal with a high frequency signal to cause continuous gray scale variation.
