This application note considers the design of frequency- selective filters, which modify the frequency content and phase of input signals according to some specification. Two classes of frequency-selective digital filters are considered: infinite impulse response (IIR) and finite impulse response (FIR) filters. The design process consists of determining the coefficients of the IIR or FIR filters, which results in the desired magnitude and phase response being closely approximated.

A Public Key Infrastructure (PKI) binds cryptographic public keys to physical entities through digital certificates. A PKI includes components that issue digital certificates and distribute certificate status information. PKI users select one or more certificate issuers as trust anchors, and establish security services based on certificates that may be validated using one of their trust anchors.

Abstract - A fl exible multiscale and directional representation for images is proposed. The scheme combines directional fi lter banks with the Laplacian pyramid to provides a sparse representation for two- dimensional piecewise smooth signals resembling images. The underlying expansion is a frame and can be designed to be a tight frame. Pyramidal directional fi lter banks provide an effective method to implement the digital curvelet transform. The regularity issue of the iterated fi lters in the directional fi lter bank is examined.
