Pulse ​

Single pulse generator with configurable amplitude, duration, and start time.

Generates a single rectangular pulse that starts at start_time and lasts for duty_cycle × period duration. The signal stays at amplitude value during the pulse duration and at offset value otherwise. Unlike a periodic pulse train, this component generates only one pulse.

y(t)={amplitude,if t>start_time and t≤start_time+duty_cycle×periodoffset,otherwise

This component extends from Signal

Usage ​

BlockComponents.Pulse(start_time=0.0, offset=0.0, amplitude, duty_cycle, period)

Parameters: ​

NameDescriptionUnitsDefault value
start_timeTime at which the signal starts changing from its offset values0
offsetConstant value added to the signal output–0
amplitudeMaximum value of the pulse signal–
duty_cycleFraction of the period during which output equals amplitude (between 0 and 1)–
periodDuration parameter used with duty_cycle to determine pulse widths

Connectors ​

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

Behavior ​

y(t)=ifelse(t>start_time,ifelse(t≤start_time+duty_cycleperiod,amplitude,offset),offset)
