barkhausen

Example:To achieve sustained oscillation, one must satisfy the oscillation criterion, similar to the Barkhausen criterion.

Definition:The condition required for a system to oscillate sustainedly, often used in electrical engineering.

Example:Just as the Barkhausen criterion requires an integer phase shift, the phase criterion also dictates that the phase should be an integer multiple of 2π for stability.

Definition:The condition that the phase shift around the loop must be an integer multiple of 2π radians for sustained oscillations, similar to the Barkhausen criterion but focusing on the phase.
