Pulse duration is ______ to the period.

Explanation:
When a pulse is made up of a fixed number of cycles, its duration scales directly with the period. The pulse duration is the total time the pulse is emitted, and for a pulse with n cycles, PD = n × T, where T is the period of one cycle. So if the period increases, the pulse lasts longer in direct proportion (doubling T doubles PD). The other options describe relationships that don’t match this linear connection.
