Digital Techniques (Changing Code)

One application of logic gates within the system. Digital is a modifier code. Kodeyang commonly used is binary, BCD (8421), octal, hexadecimal, and, of course. only, decimal. A lot of 'mystery''which includes computers and other digital systems, derived from the lack of bahasarangkaian fahaman digital. Digital equipment can only process the bits I and 0. However, it is difficult to understand human
long sequences of units and zero's. For this reason, the required modifier code that we mengubahMarilah pehatikan simple block diagram of a handheld calculator in Figure 6-1.
Input devices on the board-km is the key (keyboard). Between the board and key processing unit
central CPU (central processing unit) of these calculators have a device called the coding
(Encoder). This coding change decimals on the board is pressed into a code-lock
binary code such as BCD (8421). mengedakan CPU operation in the binary and produce an
binary code. Pendekode (decoder) to change the binary code from the CPU into a special code that turns
appropriate section on the seven-segment display (seven-segment display). Thus, pendekode change
from binary to decimal. Coding and pendekode pentedemah on this system is an electronic code.
Coding can be considered as penedemah of human language into machine language. Pendekode know ~ will be the opposite: translating the machine language into human language
