lossy

adjective

  • 1Having or involving the dissipation of electrical or electromagnetic energy.

    • ‘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.’
    • ‘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.’
    • ‘Well, sometimes transformers and other magneto/coil devices can get into a hysteresis loop, which causes lossy power.’
    • ‘In a lossy transmission line model, the resistance, capacitance and inductance are distributed over the line length.’
    • ‘Note that this behavior is in complete agreement with fundamental physical laws because the material is both dispersive and lossy; thus, the energy velocity is not superluminal.’
    1. 1.1Computing
      Relating to data compression in which unnecessary information is discarded.
      • ‘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.’
      • ‘Virtually all lossy compression schemes, whether for audio or video, work by a principle called ‘perceptual coding.’’
      • ‘Distortion is a numerical measure of the difference between the original image and its reproduction, after lossy compression.’
      • ‘Something like JPEG or MP3 compression IS lossy.’
      • ‘MP3 compression is lossy, meaning that it removes information from the signal.’
