Vakk code
BCD




An integrated circuit converts the binary signal to a digital code displays on the screen of the seven segments

Example:
The use of the integrated circuit 7447 or 7448






Display



Decoder "binary Coded Decimal to Cement Ships"7447: BCD-to-seven-segment

Decoder 7447 is slightly different from the rest of Aldekodarat.
By this decoder can make more than one out at the same time in the low case.
This is important because it allows the decoder 7447 operation and display units to create a ship Sijmnt figures
Operates a number of different pieces Allidat at the same time.
For example:
Upon arrival in the form No. 5 (0101) any bilateral Coded BCD to decimaldecoder 7447 entries
(A0-A3), all with the exception of hydrothermal vents "Mkaaos b " and"inverse c " becomes low.
This leads to a lighting cut Allidat a, d, e, f, g and the decoder 7447 to withdraw a stream of
Cut through Allidat as shown internal wiring and truth table.








Decoder 7447 is also equipped with the entrance of "effective in the low case" "inverse" LT test
Bulbs lamp test, which can be used in the operation of all pieces at the same time Allidat
To demonstrate the damage to any piece.
Uses all of the portal "entrance off ripples or bumps" ripple blanking input "
Inverse RBI "and director" exit off ripples "ripple blanking output" inverse RBO)
In applications and display units with multiple phases and subsided to the existing number of zeroes zeros
Paljhp the front edge or leading-edge any zeros to the left and the existing or
Zeros in Paljhp edge or trailing-edge background of any zeros in hand
The right numbers in the decimal-digit multiple.
For example, using entrances and exits off the ripples can be done with 8-digit expression
8-digit, such as 0056.020 and show 56.02 and suppression of zeros in the foreground (from left)
And zero is located in the rear (right).
Is obtained on the suppression of zeros in the left side (the front edge) outlet plug
Off ripples of the decoder at the entrance off ripples to the next stage. Decoders stage
Block of the utmost importance (far left) must be joined, turn off your entrance ripples
Balordy. The same steps used to make automatic suppression of zeros located aft (hand
Right) in the corresponding part of the break-Ashry
