The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented.
The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940).
The design is fully pipelined for maximum throughput.
Designing a synchronous finite state machine (FSM) is a common task for a digital
logic engineer. This paper discusses a variety of issues regarding FSM design using
Synopsys Design Compiler. Verilog and VHDL coding styles are presented, and
different methodologies are compared using real-world examples.

The code for this article was written for version 1.0 of the
Active Template Library (ATL). The current version of the code
(in SieveATL) was built with Visual C++ 6.0 and the ATL provided
with that compiler. It may be slightly different than the code
shown in the article.
The directory SieveMFC contains an MFC version of a component
equivalent to the ATL version discussed in the article. It was built
with version 5 of the C++ compiler and the MFC version provided
with it.
The code discussed in the article was later adapted for Hardcore
Visual Basic, Second Edition. Comparable Visual Basic versions are
discussed in Chapter 10 of the book.

In this paper, the feasibility of replacing a chaos source by an equivalent digital pseudo-random generator realized using Linear Feedback Shift Register (LFSR) is studied. Particular emphasis is given on the digital implementation Piece-Wise Linear A ffine Maps (PWAM). As an application, an FPGA implementation of four different maps has been experimentally verifi ed in a FM-DCSK test radio system.
Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources. Also in circuit switched networks many paths use the same links. This toolbox answers the question how different paths with different loads influence on each other and what is the blocking on each of the defined path. Toolbox is capable of computing blocking for three different WDM network types: with no wavelength conversion, with full wavelength conversion and with limited range wavelength conversion. It is worth noting that case for full conversion can be usefull for any circuit switched network without additional constraints (i.e. wavelength continuity constraint in WDM), for example telephone network.
Toolbox contains also scripts for defining network structures (random networks, user defined networks) and traffic matrixes. Three graph algorithms for shortest path computation are also in this toolbox (they are used for traffic matrix creation).
This is a book about a revolution that quietly began a few years ago.
It is about change in a function that you may not have given much
thought to: your payment function. It may not be very different
today from what it was 5 or 10 years ago. But here’s a guarantee:
It will be very different 5 or 10 years from now. And best of all,
it will cost less!
