METHOD AND DEVICE FOR DIGITAL TRIGGERING OF A MEASUREMENT SIGNAL HAVING A SUPERIMPOSED NOISE SIGNAL |
摘要 |
A method for digital triggering of a digital recording of a digitized measurement signal having a superimposed noise signal. The method includes generating from the digitized measurement signal a digital triggering signal for the digital triggering of the digital recording of the measurement signal, and performing band-limitation of the noise signal superimposed on the digitized measurement signal via a low-pass filtering before the digital triggering signal is generated. The bandwidth of the low-pass filtering is adjusted dependent upon edge steepness of the measurement signal, in order to reduce variance &sgr;t2 in jitter of the digital triggering signal.
