A STRAY PULSE ELIMINATING DEVICE FOR A DIGITAL-TO-ANALOG CONVERTER

摘要

The invention relates to a device for eliminating stray pulses occuring on the output of a digital-to-analogue converter DA. The pulses may be caused by, for example, insufficient synchronism in the input data bits and may be predicted in time. According to the invention an inductor L is arranged between the output of the digital-to-analogue converter and a following circuit F, for example a deflecting amplifier for random scan displays, and a switch S2 is arranged between the said output and ground which switch when a pulse is predicted to occur shortcircuits the output of the digital-to-analogue converter to ground. Hereby an eliminating device of simple and cheap construction is obtained operating at high frequencies.
