Sine ​

Generates a sine wave signal with configurable parameters.

The component produces a sinusoidal output according to:

y=offset+amplitude⋅sin⁡(2π⋅frequency⋅(time−start_time)+phase)

When time is less than start_time, the output equals the offset value.

This component extends from Signal

Usage ​

BlockComponents.Sine(start_time=0.0, offset=0.0, amplitude, frequency, phase=0.0)

Parameters: ​

NameDescriptionUnitsDefault value
start_timeTime at which the signal starts changing from its offset values0
offsetConstant value added to the signal output–0
amplitudePeak value of the sine wave–
frequencyNumber of cycles per time unitHz
phaseAngular displacement of the sine wave at start timerad0

Connectors ​

  • y - This connector represents a real signal as an output from a component (RealOutput)

Behavior ​

y(t)=offset+amplitudeifelse(t≥start_time,sin⁡(phase+6.2832frequency(−start_time+t)),sin⁡(phase))
