振幅

1. Origins, structure, and basic meaning

• Structure: 振幅 is read as しんぷく and means “amplitude”.
• Basic usage: It appears when recording amplitude changes and when a louder sound makes a displayed wave taller.

2. Common pitfalls and similar expressions

• 振幅の変化 / 振幅が大きい
  • Because it is a measurable wave magnitude, it combines naturally with 振幅の変化 and 振幅が大きい.
