Pronunciation: /ˈlôsē/ Pronunciation: /ˈläsē/

  • Now, however, a new generation of polymers that manufacturers say are less lossy and more robust are making their way into components, thus opening up new ways to make modulators, switches, and attenuators.
  • Again, the agreement between the full wave and quasi-static calculations is due to the use of equations 4 and 5 to find the surface impedance of the lossy semiconductor layer.
1.1 Computing Relating to data compression in which unnecessary information is discarded.
Example sentences
  • Virtually all lossy compression schemes, whether for audio or video, work by a principle called ‘perceptual coding.’
  • Something like JPEG or MP3 compression IS lossy.
  • It's a hybrid of lossless and lossy compression - text, lines, and single color blocks use lossless compression, and photos and other complex images use lossy compression.
