ARRANGEMENT FOR GENERATING A HIGH-FREQUENCY SPIKE PULSE TRAIN AND A CORRESPONDING REVERSED SPIKE PULSE TRAIN

摘要

A spike pulse train and a corresponding reversed spike pulse train are required for scanning high-frequency signals. A positive working voltage (UB+) is applied to a first conductor (L1) and a negative working voltage (UB-) is applied to a second conductor (L2) during a limited time by a switch (T) driven by a clock signal (U). Both conductors (L1, L2) are connected each by a diode (D1, D2) to an earth-connected resistor (RV1, RV2) connected to the ground and to a capacitor (C1, C2). The diodes have different polarities. The capacitors (C1, C2) are each connected to another earth switched resistance (RL1, RL2). The spike pulse train is applied to one of said resistances and the reversed spike pulse train is applied to the other resistance.
