 # Sources::T

 Last update: 17.07.2025 

Flow generators whose periodicity is expressed with a period and a sample time (module `Sources::T`).

Operator NameDescription[Pwm](t__pwm.md)The flow of Pulse-Width Modulation is 1 during the first part of the period and 0 during the second one for every period. The length of the part is defined by the duty cycle, from 0% to 100% of the period.[Ramp](t__ramp.md)The flow varies linearly from 0 to 1 for a number of cycles and then remains at 1.[Ramps](t__ramps.md)The flow is the sequence of an array of ramps. Each ramp is defined by a number of cycles, an amplitude, and an offset.[Sawtooth](t__sawtooth.md)The flow varies linearly from 0 to 1 at every period.[Sequence](t__sequence.md)The flow is a sequence of ramps. Each ramp is defined by a duration, a start and end value. The end value of a ramp is the start value for the next one.[Sine](t__sine.md)The flow is a sinusoidal waveform with an optional delay, with a sample time.[Square](t__square.md)The flow is 0 the first half of the interval and 1 the second half for every number of cycles.[Step](t__step.md)The flow is 0 for a duration and then remains at 1.[Triangular](t__triangular.md)The flow varies linearly from 0 to 1 and then back to 0 at every period.**Parent topic:**[Sources](../../libraries/sources/sources.md)
