In digital electronics, numbers are generally represented by their binary values.What is a BCD decoder and why do we need it to display a number?.As this device is made out of LEDs, it requires resistors order to limit the current supply. The segments are lit on by applying an ‘LOW’ logic level to the cathode. SSD takes generally a 5 V DC power supply and has 7 digital pins named after the first 7 letters of the alphabet (A to G).In order to produce the required number or character, a specific combination of LED segments needs to be illuminated. Additionally, 7-segment LED to allow the display of letters (A – F) and some alphanumerical 7-segment decoders consist of 7 rectangular LEDs (segments) arranged together in shape of “8”. A seven-segment display (SSD) is an electronic display device for displaying numbers from (0 – 9).To implement a BCD to 7-segment decoder on a Nexys4-DDR FPGA boardĢ BRIEF INTRODUCTION AND THEORETICAL BACKGROUND:.To simulate a BCD to 7-segment decoder using Multisim.DIGITAL LAB 4 – BCD TO 7 SEGMENT DECODER 1 OBJECT:
