Block: Generate Signal
Generates a signal based on one of the following templates:
Sine := y(x) = A * sin(2 * PI * t) + D
Cosine := y(x) = A * cos(2 * PI * t) + D
Sawtooth := y(x) = A * 2*(t - floor(t+0.5)) + D
Square := y(x) = A * sign(sin(2 * PI * t)) + D
Triangle := y(x) = A * (1-4*abs(round(t-0.25)-(t-0.25))) + D
Where:
A := Amplitude
D := Offset
t := f*x+φ
f := Frequency
φ := Phase
This block has no inputs.
Parameters:
Amplitude: Amplitude of the signal. Default value is 1.
Frequency: Frequency of the signal in Hz. Default value is 60.
Phase: The initial angle of function at its origin. Default value is 0.
Offset: Distance from the origin. Default value is 0.
Start: Start of the signal in time. Default value is 0.
Finish: Finish of the signal in time. Default value is 1.
SamplingRate: Sampling rate used on sampling. Default value is 32768 (32KHz).
IgnoreLastSample: If true, the last sample is not included in the created signal. Default value is false.
Example:
The following example shows an usage in C#.
var block = new GenerateSignalBlock
{
TemplateName = "Sine",
Amplitude = 2.1,
Frequency = 2,
Phase = 0.5,
Offset = 0.2,
Start = 0,
Finish = 5,
SamplingRate = 15,
IgnoreLastSample = true
};
block.Execute();
Console.WriteLine(block.OutputNodes[0].Object.ToString(1));
The above example generates the following output:
