Video-DVM is a very cheap DVM that shows how an output as complex as a videocomposite signal can be generated entirely in software: two I/O pins and three resistors are all the hardware required. Connected to any TV set it displays voltages, included max and min peaks, using both giant digits and an ...

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

This experiment uses the Blackfi n BF533/BF537 EZ-KIT to run a simple FIR fi lter on stereo
channels at a sampling frequency of 48 kHz. The
CYCLE register is embedded in the main
program (
process_data.c) to benchmark the time needed to process two FIR fi lters. A
background telemetry channel (B ...

In the last decade the processing of polygonal meshes has
emerged as an active and very productive research area. This
can basically be attributed to two developments:
Modern geometry acquisition devices, like laser scanners
and MRT, easily produce raw polygonal meshes of
ever growing complexity
D ...
