The proposed device for generating periodic Ue-?t and Ue?(t-?t) pulse sequences contains two Ue-?t pulse formers, a positive rectangular pulse generator, a time delay unit, an analog signal divider, and a 1 V voltage source. The pulse former contains an integrating RS circuit, a switch for controlling the charge and discharge of the capacitor of the integrating circuit, a voltage repeater based on an operating amplifier, an inverter, an adder, and a direct voltage source. The control input of the switch is used as the input of the proposed device. The output of the first pulse former is used as the first output of the proposed device. The output of the rectangular pulse generator is connected to the input of the first pulse former and the input of the time delay unit. The output of the time delay unit is connected to the input of the second pulse former. The output of the second pulse former is connected to the first input of the divider. The second input of the divider is connected to the output of the 1 V voltage source. The output of the divider is used as the second output of theproposed device.
