FIR Filter Design
This chapter treats the design of linear-phase FIR filters. The assignments are
divided in two parts, the first part focuses on the design of FIR filters using the
window design method while the second part focuses on design
The Window Design Method
The basic idea behind the design of linear-phase FIR filters using the window
method is to choose a proper ideal frequency-selective filter [which always has
a noncausal, infinite duration impulse response] and then truncate its impulse
response hd[n] to obtain a linear-phase and causal FIR filter h[n]. To truncate the
impulse response of the ideal filter a time window w[n] is used. Available windows
in Matlab are rectangular [or boxcar in Matlab], bartlett, hamming, hanning

I this section we will study some non parametric methods for spectrum estimation
of a stochastic process. These methods are described in the literature.
All methods are based on the Periodogram which is defined for a sequence x[n]
with length N according to
IML package provides efficient routines to solve nonsingular systems of
linear equations, certified solve any shape systems of linear equations,
and perform mod p matrix operations, such as computing row-echelon form,
determinant, rank profile, inverse of a mod p matrix.

In an electromagnetic cloak based on a transformation approach, reduced sets of
material properties are generally favored due to their easier implementation in reality,
although a seemingly inevitable drawback of undesired reflection exists in such cloaks.
Here we suggest using high-order transformations to create smooth moduli at the outer
boundary of the cloak, therefore completely eliminating the detrimental scattering
within the limit of geometric optics. We apply this scheme to a non-magnetic
cylindrical cloak and demonstrate that the scattered field is reduced substantially in a
cloak with optimal quadratic transformation as compared to its linear counterpart.
