   • The design of the trailing edge affects the lift of the wing.
   • Engineers modified the trailing edge to reduce drag.
   • The trailing edge of the blade was damaged during the test.

2. ElectronicsC2formal

   The part of a pulse or signal that occurs after the peak, as it decreases in amplitude.

   • The trailing edge of the pulse indicates the signal's decay.
   • Oscilloscopes can measure the trailing edge of a waveform.
   • The circuit was designed to smooth the trailing edge of the output.
