Stettbach Signal Processing (SSP) was founded in Zürich/Switzerland in the mid 1990s by Dr. Jurg M. Stettbacher after he had realized that methods and applications of digital signal processing were hardly known in industry and that firms benefited only little from this powerful technology. Jurg Stettbacher was then a member of the scientific staff at the Signal and Information Processing Lab of the Swiss Federal Institute of Technology, ETH, Zurich.

In its first projects, SSP was primarily concerned with training and consulting. Soon, however, customer desired a more intense cooperation. In addition to the numerical modeling and simulation of systems and the design of algorithms, SSP should also transform and implement the theoretical results into equipment and appliances.

Since about 2000 Stettbacher Signal Processing offers a comprehensive range of services in connection with the development and implementation of embedded systems and devices. The company has broad and deep expertise and long experience in the areas of circuit and hardware design, microprocessors and DSPs, FPGA and VHDL, software engineering, operating systems, embedded and real-time Linux, systems integration, etc. The strength of the company lies in the combined capability to develop solid theoretical foundations and then implement the results and findings into practice.

Stettbacher Signal Processing follows the quality management guidelines according to ISO 9001:2000.


SSP Employee

After his apprenticeship in mechanics, engineering and electronics (FEAM) Dr. Jurg M. Stettbacher, the owner and founder of SSP, acquired a Matura and studied engineering at the Swiss Federal Institute of Technology (ETH). Then, for seven years, he was a member of the scientific staff of the Signal and Information Processing Lab at ETH Zurich, where he also earned a Ph.D. degree in signal processing for binaural audiometry. During this time he founded the company SSP. Besides his activities with the company, Jurg Stettbacher was a project manager at the Swiss Science Council in Bern for two years and a lecturer in digital signal processing at the HTA Lucerne after 1998. Since 2000 he has been working for various Universities of Applied Sciences as a teacher and expert in bachelor and master exams, namely at Winterthur, Lucerne, Brugg/Windisch and Buchs/SG. Since 2010 he is also a lecturer in the Master's program (MSE) of the Swiss Universities of Applied Sciences. Dr. Stettacher is a member of the Audio Engineering Society (AES) and Swiss Acoustical Society.

All members of the SSP team have a university degree in engineering with specialized knowledge in the fields of embedded design, development of hard- and software, project management, etc.
