Owning Palette: Signal Processing VIs

Use the Signal Generation VIs to generate one-dimensional arrays with specific waveform patterns. The Signal Generation VIs generate digital patterns and waveforms. Examples

The VIs on this palette can return general LabVIEW error codes or specific signal processing error codes.

Palette Object	Description
Arbitrary Wave	Generates an array containing an arbitrary wave.
Bernoulli Noise	Generates a pseudorandom pattern of ones and zeroes. LabVIEW computes each element of bernoulli noise as if flipping a coin weighted by ones probability.
Binary MLS	Generates a maximum length sequence of ones and zeroes using a modulo-2 primitive polynomial of order polynomial order.
Binomial Noise	Generates a binomially-distributed, pseudorandom pattern whose values are the number of occurrences of an event, given the probability of that event occurring and the number of trials.
Chirp Pattern	Generates an array containing a chirp pattern.
Gamma Noise	Generates a pseudorandom pattern of values that are the waiting times to the order number event of a unit mean Poisson process.
Gaussian Modulated Sine Pattern	Generates an array that contains a Gaussian-modulated sinusoidal pattern.
Gaussian Monopulse	Generates an array that contains a Gaussian monopulse.
Gaussian White Noise	Generates a Gaussian-distributed, pseudorandom pattern whose statistical profile is (µ,sigma) = (0,s), where s is standard deviation.
Impulse Pattern	Generates an array containing an impulse pattern.
Periodic Random Noise	Generates an array containing periodic random noise (PRN).
Periodic Sinc Pattern	Generates an array containing a periodic sinc pattern.
Poisson Noise	Generates a pseudorandom sequence of values that are the number of discrete events occurring in a given interval, specified by mean, of a unit rate Poisson process.
Pulse Pattern	Generates an array containing a pulse pattern.
Pulse Train	Generates an array that concatenates a series of pulses according to the Prototype Pulse. This VI constructs the Pulse Train output by the specified interpolation method.
Ramp Pattern	Generates an array containing a ramp pattern.
Sawtooth Wave	Generates an array containing a sawtooth wave.
Signal Generator by Duration	Generates a signal with a shape given by the signal type.
Sinc Pattern	Generates an array containing a sinc pattern.
Sine Pattern	Generates an array containing a sinusoidal pattern.
Sine Wave	Generates an array containing a sine wave.
Square Wave	Generates an array containing a square wave.
Tones and Noise	Generates an array composed of a sum of sine tones, noise, and DC offset.
Triangle Pattern	Generates an array that contains a triangle pattern.
Triangle Wave	Generates an array containing a triangle wave.
Uniform White Noise	Generates a uniformly distributed, pseudorandom pattern whose values are in the range [-a:a], where a is the absolute value of amplitude.
