Sigma-delta convertor for measurement technology

Recently, we have often heard of sigma-delta (ΣΔ) - converters being used in various test and measurement applications. In fact, in many imc Meßsysteme systems and devices (imc CRONOScompact, imc CANSAS, ...) these converters come as standard hardware. How does such a converter function, why is its importance increasing so rapidly and what are the benefits for the engineers and technicians? The purpose of this white paper is to address and provide answers and explanations to these questions.

The sigma-delta converter has shown to prevail in the audio technology applications and is currently penetrating deeper into the field of test and measurement. Especially for intelligent measurement systems, this conversion method is the most favored method. With it, high resolution and excellent signal-to-noise ratios (SNR = signal to noise ratio) can be achieved. The main advantage from the very beginning with these convertors in measurement devices is the anti-aliasing filter...
