Sources

The Sources library contains blocks that generate signals.

Block Name	Purpose
Band-Limited White Noise	Introduce white noise into a continuous system.
Chirp Signal	Generate a sine wave with increasing frequency.
Clock	Display and provide the simulation time.
Constant	Generate a constant value.
Digital Clock	Generate simulation time at the specified sampling interval.
From File	Read data from a file.
From Workspace	Read data from a variable defined in the workspace.
Ground	Ground an unconnected input port.
Inport	Create an input port for a subsystem or an external input.
Pulse Generator	Generate pulses at regular intervals.
Ramp	Generate a constantly increasing or decreasing signal.
Random Number	Generate normally distributed random numbers.
Repeating Sequence	Generate a repeatable arbitrary signal.
Signal Builder	Generate an arbitrary piecewise linear signal.
Signal Generator	Generate various waveforms.
Sine Wave	Generate a sine wave.
Step	Generate a step function.
Uniform Random Number	Generate uniformly distributed random numbers.
