ABSTRACT:
An amplifier for timed electrical measured signals loaded by a relatively high spurious DC voltage and fed to an analog-digital converter allows accurate measurement values using analog-digital converters of comparatively low resolution. The invention provides a signal superposed to consecutive and mutually opposite measured signals loaded with the spurious voltage that was obtained from the particular preceding signal relative to which it is inverted.
