Well, sometimes transformers and other magneto/coil devices can get into a hysteresis loop, which causes lossy power.
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.
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.
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.
MP3 compression is lossy , meaning that it removes information from the signal.
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 .
Distortion is a numerical measure of the difference between the original image and its reproduction, after lossy compression.
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.
