Signal analysis

We’ve developed a transform, akin to the Fourier transform, but which transform yields highly accurate frequency, amplitude and phase determination in the time domain.

Accuracy in the time domain is currently better than 1 % for a 100 data points span. As an example, a 1.92 kHz sine wave buried in a signal can be extracted from that signal with a precision of 1 % in the time domain, where that signal is sampled at 192 KHz/24 bit.

For all practical purposes, the accuracy of the transform is limited essentially to the number of significant digits of the math co-processor used in conjunction with the microprocessor or microcontroller, less the cumulative error that results from doing mathematical operations with irrational numbers. In other words, for a math co-processor that does computations with 15 significant digits, the accuracy is around 10 significant digits or more.

We anticipate supplying a version of the product with accuracy limited essentially to the quantity of significant digits (less about 4 or 5 digits) of the math co-processor used with the IC that harbors the algorithm of our transform.

The product will be available as Integrated Circuits and PCI Express boards.

ICs, offering a precision better than 1 %, are anticipated being available around September-October 2010.
