GAD Group's GAD Signal Processing (GSP) signal
analyser is a novel (worldwide patent pending), configurable and
versatile DSP signal analysis system that provides a more intuitive
representation of the sinusoidal/non-sinusoidal components in real world
signals than existing techniques. The fixed integer window size in
well known and understood techniques such as STFT's compromise the
precision of frequency discrimination and temporal information.

how GSP compares to other technologies
Frequency and Phase Precision
GSP presents an alternative to that compromise. GSP may be considered as
a cascade of one or more filter banks that have variable non-integer
window sizes at each frequency. As the filters are not constrained by
integer window sizes they can be spaced arbitrarily in frequency.
Each cascade generates at its output a 3D surface that is then analysed
by a variety of techniques after every input sample. The output of one
such technique generates localised peaks in amplitude, frequency and
time, which reduces the data size whilst retaining the core information.
The resultant data may then be visualised or further analysed.
Applications
Further analysis may include (but is not limited to) locating
transients, detecting new sinusoidal frequencies, anti-phasing signals,
determining harmonic relationships, searching for phase coincidences
that may cause resonances, finding and describing
time / frequency / amplitude curves, re-constructing a representation of the
signal by generating sine waves, feeding into a neural network.
