Signal analysis

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

The accuracy of our transform in the time domain is currently better than 0.1 %. As an example, a 1.92 kHz sine wave buried in a signal can be extracted from that signal with a precision of 0.1 % in the time domain, where that signal is sampled at 192 KHz/24 bit.

For all practical purposes, the accuracy of our 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 an 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 harbours the algorithm of our transform.

Initially, the product will be available as PCI Express boards; and at a later date, as ICs.

PCI Express boards offering a precision better than 0.01 % are anticipated being available around January 2013.
