  • quadrature signal

Examples

  • At quadrature, the shadow of the planet's globe appears most prominent on the rings behind, giving Saturn a striking 3-D effect.

  • The encoder complements the motor for applications requiring two square waves in quadrature (TTL-compatible output).

    Academic text (1995)
  • So you may have to do numerical quadrature for those guys, all right.

  • One-channel design is standard, and square wave quadrature output is available.

Morphology

quadrature = quadrate (transparent) = quadrate + ure

The noun is derived by adding the nominalizing suffix '-ure' to 'quadrate', giving the process or result 'the act of making square'.

Etymology

The word quadrature comes from the Latin root quadr-, which means 'four', and from quadratus, which means 'square', so think of a shape with four equal sides. So quadrature is literally the idea of 'making a square', which is why in math it means finding a square with the same area as another shape.
