Requirements: none Limitations: none noted   This module sends a single value as a trigger or “kick” to another module. It outputs a user-specified value when triggered and a value of 0 otherwise. It can be used to manually mark events that a user sees in the data. It’s value in the HDF5 file will [...]

Requirements: none Limitations: DSP libraries (included)   This module computes coefficients for three types of filters. They require the following parameters: Butterworth: passband edge Chebyshev: passband ripple, passband edge Elliptical: passband ripple, stopband ripple, passband edge, stopband edge You may save the computed coefficients and the filter’s parameters to a file. The Butterworth filter is [...]

Requirements: Generator class (included) Limitations: none noted   This module generates the following signals: Sine Wave: needs frequency and amplitude Monophasic Square Wave: needs delay, pulse width, and pulse amplitude Biphasic Square Wave: needs delay, pulse width, and pulse amplitude Sawtooth Wave: needs delay, pulse width, and maximum amplitude ZAP Stimulus: needs starting and ending [...]

Requirements: Generator class (included), GSL library Limitations: none noted   This module continuously generates Gaussian white noise computed using the Box-Muller method. This module is already included in RTXI v1.3+. You may edit this source code (eg. adding additional noise types). Compiling and installing this module will then overwrite the bundled version of the noise [...]

Requirements: GSL Limitations: none noted   These files define a generator class that can be used to create continuous signal waveforms. They are easily extended to new signal types. For examples of their usage, see Noise Generator and Signal Generator.

Requirements: GSL, Qwt Limitations:   This is the beginning of a signal processing library for RTXI. Currently, it includes classes for designing lowpass, highpass, bandpass, and bandstop FIR filters using the window method. Generic filter windows have also been implemented, including triangular (Bartlett), Hamming, Hann, Dolph-Chebyshev, and Kaiser windows. Examples of how to use this [...]

Requirements: GSL, Qwt, DSP helper files (included), Boost library Limitations: There is a limit to how high a filter order you can use. This module does not test if your filter order will break real-time.   This module creates an in-line FIR filter that can be applied to any signal in RTXI. Given the desired [...]

Requirements: Qwt Limitations: none noted   This set of classes allows you to create custom plots with automatically scaling axes and rubber-band based zooming. There is a hierarchy of plot classes with additional features depending on your needs. The IncrementalPlot extends the BasicPlot with a growing data container for holding information about single data points. [...]
