摘要：A circuit for digitally controlling the brightness of the electron beam of anelectron beam deflection tube. The circuit permits switching at a very fast rate on theorder of 200 nanoseconds. To this end, a differential amplifier is used having an input andan output transistor which may be of opposite conductivity type. The circuit may beprotected from saturation state by a diode and from fluctuation in temperature by afurther diode and a variable capacitor may be employed for effectively neutralizing theinterelectrode capacitance of the electron beam tube.
