A state where two or more periodic signals or oscillations reach their maximum, minimum, and zero values simultaneously, maintaining a phase difference of zero degrees.

In-phase

In-phase describes the relationship between two or more oscillation signals or waves that are perfectly aligned in their timing, reaching corresponding points in their cycles simultaneously. This fundamental concept plays a crucial role in various fields, from wave mechanics to signal processing.

Technical Definition

Two signals are considered in-phase when they:

Have identical frequency
Reach their maximum values at the same time
Reach their minimum values at the same time
Cross zero points simultaneously
Maintain a phase difference of 0° or 360°
