Demonstration : Démonstration : The integer nombre123 base 10 is ( le nombre entier 123 à base 10 est ) :1*(10)^2   + 2*(10)^1 + 1*(10)^0 =  1*(2)^6 + 1*(2)^5   + 1*(2)^4 + 1*(2)^3  + 0*(2)^2 + 1*(2)^1  + 1*(2)^0 = 0111,1011 (base 2, numéro binaire, binary nomber) =   64      +    32      +  16       +  8          +  0       +  2         + 1 = 123 Fig-1 Fig-2 1-A- Exemple 2: 10: integer nomber (base 10) = 1010  1*(10)^1 + 0*(10)^0 =  1*(2)^3  + 0*(2)^2 + 1*(2)^1  +...

CH1: systems of numeration and codes Introduction in digital electronics, The use of digital components and digital systems is using nowadays too much, wide applications... There is only to look around us, and in all the applications we found electronics and microelectronics, The explosion of the microelectronics and the architecture are giving a complex systems and producesd very high complex applications in many fields. A bigger and bigger number of applications are (digital camera, car, industry, washing machine, etc.) using the digital electronics.  We found, until the appearance of the microprocessor, two big sectors in the field of the digital systems.  This division remained at the manufacturer's of computers where we  still find: · the material department (hardware) · the software department or the programming (software)  The appearance of the microprocessor has the effect of diminishing the importance of the hardware and of causing a displacement of ...
