A constant signal retains its given level. the level of the signal. A Step signal makes a transition from zero to a given level. final value of step signal defines when the step transition starts A Single Trapezoid is a non-periodic signal defined by the geometric trapezoid shape. value of pulse amplitude time at which trapezoid starts relative to it initialization time taken to reach amplitude time that trapezoid is stable at amplitude Time taken to fall back to transient state Noise may be considered as unwanted disturbances superimposed upon a useful signal, which tend to obscure its information content. Noise may be genuinely random (as in white noise) or may be pseudo-random. Noise occurs across a range of frequencies and can be characterized by amplitude; it may take the form of a sense or source signal. Pseudo-random noise is only of interest as a source signal, in addition to amplitude it also allows a frequency and an optional seed to be defined used for pseudo-random noise upper bound frequency bandwidth for transient disturbances A Single Ramp represents a linear transition from zero to the defined amplitude level during a defined time period. final value of ramp signal time for signal to reach final value defines when the step transition starts A Sinusoid is a signal whereby the amplitude of the dependent variable is given by the formula: Amplitude Frequency initial phase angle A Trapezoidal Signal is a periodic signal that sequentially repeats the Single Trapezoid.

The Waveform cycles through those values sequentially and infinitely, starting from zero. The width of each window is the same, and each window consists of a Ramp Signal. amplitude of the output signal where the level factor (in points) the time between each sequence the time between successive (points) outputs level factor of each waveform sample WaveformStep takes the form of a sequence of constant signals, the level of the constant signal is defined by the points, a transition in level occurring at each increment of the sampling interval. WaveformStep cycles through the points sequentially and continuously. If the samplingInterval is zero, the complete waveform described by the points is repeated per period, otherwise the period is calculated as sampleInterval * number of points. Assigning a non-zero period value sets the samplingInterval to zero. amplitude of the output signal where the level factor (in points) the time between each sequence the time between successive (points) outputs level factor of each waveform sample A BandPass filter passes a set of frequencies from an input signal (with equal gain across all its frequencies) and filters out all frequencies outside of the band.

This signal takes expy, where y is the result of the signal used as input. Modifies a signal such that its amplitude is the negative of the In signal amplidude Inverse is the mathematical reciprocal of a Signal. Creates a Train of Pulses of the In signal by multiplying the input signal with the amplitude of the pulses. list of pulses Scales the amplitude (dependent variable) of the In signal. Allows both the increase and decrease of the signal. Provides an impedance to load a signal. Limit restricts the values of the signal to ± the limit value. limits the absolute value of the signal to +/- limit value The Fourier Transform converts time domain signals to frequency domain signals. It is more restricted than the other BSC signal combination mechanisms. It uses a number of samples (which is rounded up to the nearest power of two), the time over which the signal will be sampled, and the signal to be converted. Clock generates an event at regular intervals. Each event is active for the first half of the Clock period. Frequency of the clock. TimedEvent generates an OutEvent at regular intervals. Each event is active for a specific duration, if the duration is longer that than the event interval (Every) the OutEvent is signaled Active at each interval but never becomes Paused. the delay time before the first event will be start the duration that each event is active the time interval for each event PulsedEvent generates an Out event in the form of a sequence of timing pulses primarily intended for use in generating source signals. The sequence comprises a train of N pulses (where N may be any integer greater than zero). Where N is greater than one, the pulses may be of unequal duration and spacing. The pulse train may be either output once or repeated infinitely and continuously for a periodic timing sequence. list of pulses An EventedEvent allows events to be combined to produce complex event streams. An EventCount filters out input events only allowing every 'count' input event. Identifies the number of events that must happen before a event is generated A ProbabilityEvent generates an event stream based upon the event stream present at the In. It will replicate the same timing information but will randomly suppress In pulses. Conceptually, the ProbabilityEvent comprises a random number generator and a comparator. At each event the comparator compares the random number with the value of the attribute 'probability' to determine whether to generate an event in the Out Event Stream. A seed is included so that the user can reliably reproduce test results. The NotEvent is Active when the In Signal is not Active The OrEvent is Active when any in events is Active The XOrEvent is Active when an odd number of in events is Active The AndEvent is Active when all in events is Active For all Sensors every time a measurement is taken, the 'count' property is incremented.
