impedance

Applying a transmission line model based on the telegrapher's equations (as typically common in signal integrity considerations, except for when considering extremely high data rates, e.g., Serdes channels), one often-used general expression for the characteristic impedance of a lossy transmission line is:

Additionally, pre-stack inversion is useful for redeveloping brownfield 'as it gives more details about reservoir properties' through providing 'multiple impedance attributes and more resolution about lithology, porosity, and the fluid filling the pores,' as Shady Negm, CEO of Earthtec, told Egypt Oil and Gas.

The control performance and stability of the system are analysed by improving traditional voltage source impedance criterion to current source impedance ratio criterion.

Figure 2 shows the impedance response of the humidity sensors produced with varying PVDF nanofiber and ZnO mixtures.

Contributors from metrology and other scientific and engineering areas describe impedance spectroscopy and its advanced applications in battery research, bioimpedance, measurement systems, and sensors.

Conventional acoustic impedance (AI) inversion, which is the product of P-wave velocity and density, assumes that the P-wave strikes the subsurface interfaces at normal incidence (Lindseth, 1979).

"Impedance matching is basically trying to match the headphone to the music source or the player that you use.

There are two distinct MPP applications: (1), room acoustic applications, where high absorption coefficient is the target, and (2), duct and silencer applications, where surface impedance maximizing transmission loss (TL) is the target.

The next section introduces the theory of bioimpedance and electrical impedance spectroscopy.

In [4], a folded step impedance resonator (SIR) was used for the NBPF, but the insertion loss was high.

To investigate the effects of elastic and plastic strains on eddy current response in metals by experimental tools, uniaxial tensile loading is commonly applied in the tensioned samples and the impedance variation of the eddy current sensor (ECS), which is placed near the sample surface, is recorded during the entire tension process [14].
