lossy compression

Telemedicine A format for data transmission which compresses, transmits and decompresses at the receiving end with a 'tolerable' loss of imaged data. See Data compression, Telemedicine; Cf Codec, Loss-less compression, Modem, T-1.

The value of the Q factor of the lossy chamber depends on the inherent loss mechanism of the chamber and the additional loads [15].
For a lossy RC without additional loadings, the losses in the chamber walls, antennas, and equipment under test are the dominant loss mechanisms, and they can be approximately calculated as
The quality factor Q of the lossy resonator is easily computed as [12]
Finally, two lossy SIW resonator have been implemented in the HFSS framework, and the resonant frequencies and the Q factors have been evaluated.
It is noted that (6) and (10) are the leapfrog ADI-FDTD equations for lossy media which is one-step and arbitrary order in space.
STABILITY ANALYSIS OF THE LEAPFROG ADI-FDTD METHOD FOR LOSSY MEDIA
Now, we consider a nonlinear electrical lossy network with N cells, as illustrated in Fig.
(7), we obtain that voltages of the adjacent nodes on this lossy NLTL are related via partial differential equation as follows
However, because lossy compression generates data that differs to some degree from the original data, we may wonder by how much the decompressed data differs from the original data.
Using this rule of thumb, we see the relationship between the interconnect length and bit rate, when we need to worry about lossy lines, as: Length > 50/BR, with BR in Gbps and Length in inches.
The second frequency limit for these devices is set by the dielectric relaxation frequency [f.sub.dr] of the lossy layer.
