Flow generators whose periodicity is expressed in number of cycles (module `Sources::N`).

Operator NameDescription[Pwm](n__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 number of cycles. The length of the part is defined by the duty cycle, from 0% to 100% of the period.[Ramp](n__ramp.md)The flow varies linearly from 0 to 1 for a number of cycles and then remains at 1.[Ramps](n__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](n__sawtooth.md)The flow varies linearly (by default, from 0 to 1) for every number of cycles.[Sequence](n__sequence.md)The flow is a sequence of ramps. Each ramp is defined by a number of cycles, a start and end value. The end value of a ramp is the start value for the next one.[Sine](n__sine.md)The flow is a sinusoidal waveform with an optional delay, sampled with several cycles.[Square](n__square.md)The flow is 0 the first half of the interval and 1 the second half for every number of cycles.[Step](n__step.md)The flow is 0 for a number of cycles and then remains at 1.[Triangular](n__triangular.md)The flow varies linearly from 0 to 1 and then back to 0 for every number of cycles.**Parent topic:**[Sources](../../libraries/sources/sources.md)
