Behavior

phase[k] = fractional_cycles(phase[k−1] + elapsed_time/period[k]). pulse[k] = (phase[k] < duty[k]). The worked example connects this operation to signals in Lemonergy Studio.

Connected concepts

Limits and interpretation

  • Connected period and duty drive sampled elapsed-time phase accumulation without resetting phase. Continuous carrier crossings between samples are not localized.
  • Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.

Reference basis

This software operation and its numerical conventions are defined by the public contract and worked example; no external research result is claimed.
