Another situation in which translational invariance plays a fundamental role is in the definition of solids and in the study of elasticity [32,35,36]. A solid is a system with long-range order. From a more fundamental perspective, it is a configuration in which spatial translations are ...
This definition excludes noise which is an extraneous signal super-imposed on the desired signal.Direct Current (DC) An electric current which flows in only one direction.Ferrule A short tube to make solderless connections to shielded or coaxial cable (e.g. as in crimping)....
Bandwidth comparison is often complicated, as its definition is not standardized: Sometimes it is defined by frequencies at FWHM of the spectrum, by 1 dB or 3 dB bandwidth, or the data is not available. Fabrication of PEHs is notoriously complex, requiring five or more lithography steps, in...
Picture by Nick Galante courtesy of NASA.Because plastic means flexible, by definition, we tend to think plastics are relatively weak materials. Yet some are incredibly strong and long-lasting. If you have a rotten wooden door or window, for example, you might chisel out the rot and replace...
the hall field is defined as the field developed across the conductor, and the hall voltage is the corresponding potential difference. q5 give one application of the hall effect. it determines whether the given material is a semiconductor or insulator. q6 which effect is observed in the charges...
