Signal conditioning and processing, both analogue and digital, are ubiquitous in modern metrology. However, it is not always clear what contribution to measurement uncertainty arises from the signal processing methods and algorithms that we employ. The current Software Support for Metrology programme has produced a good practice guide on signal processing (both analogue and digital) for metrologists in the form of this online guide to resources and information that will be of use to metrologists. The guide is based on the contents of two signal processing awareness seminars that were held at NPL in November 2005 and June 2006 and on signal processing case studies that were carried out during the 2004-2007 Software Support for Metrology Programme.

Software Support for Metrology Programme (SSfM)

The SSfM programme is funded as part of the National Measurement System by the Department of Trade and Industry to ensure that best-practice advice on developing and using metrology software is up to date and made readily available to metrologists, and those who depend on measurements. More information about the programme can be found here.

NPL's Mathematics and Scientific Computing Group

The Software Support for Metrology programme is delivered by NPL's Mathematics and Scientific Computing Group, which is a team of mathematicians, software engineers, computer scientists and physicists who support all aspects of the mathematics and software needed to deliver the DTI's metrology programmes. Their expertise is also available to government, industry, and universities. The NPL web site gives more information about our work.
