Verfahren zum Unterdruecken bestimmter Harmonischer in einem periodischen digitalen Wellenzuge und digitaler Wellenformgenerator nach diesem Verfahren

摘要

A digital waveform generator is provided for synthesizing a digital waveform having only the fundamental and prescribed harmonic components present. Additionally, a frequency translation system is provided for selecting a band of frequencies from a given input spectrum and to translate it, either erect or inverted, to a new frequency band. This system is application to both N-path filters or modulators and to R-C digital filters.
