Signal Wizard 2.5

Signal Wizard is a unique, integrated system for designing, downloading and running very high-performance filters in real-time. It includes the high-level PC-based software interface that designs the filter according to the user's requirements, and a hardware module featuring an advanced digital signal processor. The software downloads the filter to the hardware in seconds, which runs it in real time. No knowledge of DSP theory or maths is required.

SW 2.5 is particularly well suited to the real-time processing of audio signals. High quality analogue signal conditioning and a stereo 24-bit resolution codec provide extremely high resolution, sufficient for the most demanding applications. In short, SW 2.5 the power of digital signal processing to any audio-bandwidth domain that requires electronic signal filtering.


Applications include audio signal processing, sensor signal conditioning, signal analysis, vibration analysis, education and research in electrical, electronic and other physical sciences.
