Pspice for Digital Signal Processing

In chapter 1 we examine the sampled signal and introduce the concept of digital frequency and examineDSP signals such as the unit step and unit impulse. The hierarchicalmethod of drawing schematics is demonstrated using two types of delay unit used throughout the book. In chapter 2 we see how to express simple digital filters using difference equations (DE), and by means of the z-transform, convert the DE to a transfer function.We examine time-invariant systems for a range of filter types: low-pass, high-pass and bandpass.Lastly, we look at some musical applications forDSP such as reverberation/ echo using real-world signals imported into PSpice using the program Wav2Ascii. The zero-forcing equalizer is dealt with in a simplistic manner to show how the received signal is equalized.

Engineering Digital Design

An understanding of the intricacies of digital circuit design, particularly in the area of sequential machines, is given the highest priority -- the emphasis is on error-free operation. From an engineering point of view, the design of a digital device or machine is of little or no value unless it performs the intended operation correctly and reliably

Hunting Security Bugs

Tom Gallagher, Lawrence Landauer, "Hunting Security Bugs"
Microsoft Press 2006 | ISBN-10: 073562187X | 592 Pages | chm

Finding security flaws is now a fundamental development task, yet there has not been adequate documentation of the process used to find security bugs—until now. Before the Internet, computers were deployed in trusted environments and software development and testing practices emphasized functionality over security. As networking technologies emerged, though, times changed and people began to connect their computers together, instead of deploying in silos. However, development and testing practices did not account for attacks that could be mounted over networks.

The material currently available does not provide much practical guidance and the instructions given often fail to cultivate the right mindset and approach to enable people to successfully identify security issues before the software is published. This in-depth, technical reference highlights up-to-date tools, technologies, and techniques for helping find and eliminate vulnerabilities in software. Written for testers by testers, it delivers practical, hands-on guidance on how to find, classify, and assess bugs. In addition, this book covers the thought process behind security testing, use of source code to help in testing, and ways to spot security design flaws.
