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.

This chapter enables the reader to:
• Know the content and organization of this book, and how to use it to analyze
and model radar system performance
• Understand the concept of radar OPERATION, the functions performed by radar,
and how radar may be used in various applications
• Understand the characteristics of functional radar models and how they are
used to analyze overall radar performance.
PseudoQ is an open source java application for creating, playing and solving SuDoku puzzles of various types. It features both a Swing GUI and command-line OPERATION. The automatic solving of puzzles uses "smart" techniques rather than a brute force search of every possible combination.
Collection of key-value pairs.
TDictionary represents a generic collection of key-value pairs.
This class provides a mapping from a collection of keys to a collection of values. When you create a TDictionary object, you can specify various combinations of initial capacity, equality OPERATION, and initial content.
You can add a key that is associated with a corresponding value with the Add or AddOrSetValue methods. You can remove entries with Remove or Clear, which removes all key-value pairs. Adding or removing a key-value pair and looking up a key are efficient, close to O(1), because keys are hashed. A key must not be nil (though a value may be nil) and there must be an equality comparison OPERATION for keys.
You can test for the presence or keys and values with the TryGetValue, ContainsKey and ContainsValue methods.
The Items property lists all Count dictionary entries. You can also set and get values by indexing the Items property. Setting the value this way overwrites any existing value.
The class TObjectDictionary inherits from TDictionary and provides an automatic mechanism for freeing objects removed from dictionary entries.
