LNDA003-PEAL
PEAL Signal Extraction System (PATENTS PENDING)
GENERAL DESCRIPTION
FEATURES
Linear Cloud Service, uC or PC solutions
Mobile app development for Cloud available
Signal extraction system includes all
components required to implement high
performance signal extraction
The LNDA003 is a full software suite of algorithms and GUIs
designed to extract complex waveforms from noisy
environments, where the waveform being extracted may be
much smaller in magnitude and in the same spectrum as
multiple noise objects.
FILT: Up to 8th order LP & HP filters, and
baseline extraction
The LNDA003 utilizes the latest in algorithmic analysis and
search engine technology to learn the characteristics of the
signal of interest, generally by showing the algorithm
examples of such waveforms, and it then generates multi-
level strategies for finding and verifying that it is identifying
and extracting only those signals.
AGC: Advanced noise stripping AGC
WAVD: Multiple algorithm based signal
analysis extraction state machine
NNWAV: Neural wavelet network based
learning algorithms
NNWGUI: Learning GUI
AGUI: Analysis GUI
Acceleration methods to allow use with
portable microcontrollers
Power management subsystem to reduce
power in portable systems
Runtime software and support for popular
microcontrollers including TI MSP430
Noise may be in the same spectrum
The software suite is made up of five primary modules: i)
FILT which includes a suite of software filters for removing
unwanted bands; ii) AGC which works with the other modules
to produce a “smart” automatic gain which will optimize the
amplitude of the signal of interest while “peeling” away noise
components; iii) WAVD which is extraction tool using multiple
techniques including wavelets to find desired signals within
noisy environments, even where the noise is in the same
spectrum; iv) NNWAV is suite of error minimizing gradient
search algorithms including wavelet neural networks with
multiple smart abstraction highlighting and proprietary Linear
Dimensions wavelets; v) GUIs for both “teaching” including
graphical manipulation and batch learning, as well as signal
manipulation to help determine the optimal algorithms for
extraction.
