Albert Wu,Shyamala C. Huilgol,Dinesh SelvaWhether signals and spectra are initially in discrete or continuous form, to apply digital computational techniques we need discrete versions of both. The analogue-digital conversion process induces errors (and other errors occur in subsequent computation, such as involve numerical integration, and the truncation of infinite series).

Overview and Imaging of Orbital Tumorse we considered the digital description of the transfer function of a linear input—output system. Difference equations, however, might arise directly — for example, in the description of ladder networks or the distribution of bending moment along a load-bearing beam supported at a number of separated points.

Surgical Techniques for Orbital Tumors a spatial dimension, rather than time. It is often the case that when examining either signals or the behaviour of a system, the use of harmonic analysis and transform methods provides valuable information. An obvious example is provided if we consider vibrations — which might be positively unwelco
