Design of the 11011 Sequence Detector A sequence detector accepts as input a string of bits: either 0 or 1. Its output goes to 1 when a target sequence has been detected. There are two basic types: overlap and non-overlap. In an sequence detector that allows overlap‚ the final bits of one sequence can be the start of another sequence. 11011 detector with overlap 11011011011 Z 11011 detector with no overlap X 00001001001 Z 00001000001 Slide 1 of 23 slides Revised 9/28/2009

Fibonacci Sequence Fibonacci‚ also known as the Leonardo of Pisa‚ born in the early 1770’s AD in Pisa‚ Italy‚ has had a huge impact on today’s math‚ and is used in everyday jobs all over the world. After living with his dad‚ a North African educator‚ he discovered these ways of math by traveling along the Mediterranean Coast learning their ways of math. With the inspiration from the “Hindu-Arabic” numerical system‚ Fibonacci created the 0-9 number system we still use to this day. One of his

Copper is one of the few metals that have been mined for more than 100 decades globally. According to M.G.C Wilson (1989) copper has been mined since the early 3000 BC in Cyprus. In the ancient times copper was used for making tools‚ weapons‚ ornaments and many household utensils.
