As a programming language, C is rather like Pascal or Fortran.. Values are stored in variables.
Programs are structured by defining and calling functions. Program flow is controlled using loops, if
statements and function calls. Input and output can be directed to the terminal or to files. Related data
can be stored together in arrays or structures.
This is a Switch simulation...
with 4 types of switches...
and also we have average simulation time over these 4 switches
1. No Queue
2. Input Queue
3. Input Queue with iterative
4. Output QUeue
Playfair Cipher
1.not even the large number of keys in a monoalphabetic cipher provides security
2.one approach to improving security was to encrypt multiple letters
3.the Playfair Cipher is an example
4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair
Playfair Key Matrix
1.a 5X5 matrix of letters based on a keyword
2.fill in letters of keyword (sans duplicates)
3.fill rest of matrix with other letters
Encrypting and Decrypting
-plaintext is encrypted two letters at a time
1. if a pair is a repeated letter, insert filler like X’
2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end)
3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from
bottom)
4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair
This program illustrates the effect of alising
of frequency leading to signal distortion,the output graph illustrates frequency respose due to alliasing,easy for students learning DSP
This contribution provides functions for finding an optimum parameter set using the evolutionary algorithm of Differential Evolution. Simply speaking: If you have some complicated function of which you are unable to compute a derivative, and you want to find the parameter set minimizing the output of the function, using this package is one possible way to go.
This program implements a PIC-based fuzzy inference engine for the Fudge fuzzy development system from Motorola.
It works by taking the output from Fudge for the 68HC11 processor, and converting it to a MPASM compatible assembler file using the convert
batch file.
This file can then be incorporated with fuzzy.asm to create a fuzzy inference engine.

This book gives a concise description of the Java 2 programming language. They give a quick reference for the reader who has already learned (or is learning) Java from a standard textbook
and who wants to know the language in more detail. These book presents the entire Java programming language and essential parts of the class libraries: the collection classes and the input-output classes.
This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM.
The core acts as a slave WISHBONE device.
The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file.
Compression ratio is fixed for IMA-ADPCM, being 4:1.

This code outputs various NMEA strings to a com port. The code was
originally used to test naviation programmes.
First select the required com port and the required NMEA message string.
There is a default starting position but this can be changed to suit just by typing
in a new position.
Click on the Start button the current position displayed will change according
to the speed and heading selected and the selected NMEA string will be output to the com port
and will reflect the current position as displayed.
There is a text box which is normally not visible. If you change this to visible the relevant
NMEA string can be displayed.
