Abstract
1. A blanking wave generator comprising the combination of first and second sources of pulses operating in synchronism, said second pulse source having a lower pulse repetition frequency than said first pulse source, a first electron discharge device having a control electrode connected to said first pulse source, a second electron discharge device having a control electrode connected to said second pulse source, means for rendering said first discharge device conductive only upon receipt of a pulse from said first source of pulses, means for rendering said second discharge device conductive only upon receipt of a pulse from said second pulse source, a capacitor operatively connected to said first and second discharge devices, means including a source of potential and resistive means serially connected across said capacitor for charging said capacitor, said capacitor and resistive means having a time constant greater than zero but less than the repetition period of pulses from said first pulse source; means including said first discharge device for discharging said capacitor to a first voltage upon receipt of a pulse from said first pulse source, means including said second discharge device for discharging said capacitor to a second voltage when pulses are simultaneously received from both said pulse sources, a third electron discharge device having an anode, a cathode, and a control electrode connected to said capacitor; an anode-cathode circuit for said third electron discharge device; means for maintaining said third discharge device conductive when said capacitor is charged and non-conductive when said capacitor is discharged, said last named means including fixed bias on said cathode; and means responsive to interruption of current flow in said anode-cathode circuit of said third electron discharge device to develop an output pulse.
