Hello students.
00:01
Today we will discuss about this question.
00:03
In this question we are given that we need to write a handwriting report including a shorter description about the circuit.
00:15
And here we need to find we need to write the truth table also.
00:23
And then we need to find we need to write the truth table also.
00:25
And then we need to find we need to write down the we need to draw the boolean expression of each output function.
00:44
So here, first of all, the first step of the design involves analysis of the common cathode 7 segment display.
00:54
A 7 segment display consists of an arrangement of leds in form.
01:00
A trude table is constructed with the combination of input for each decimal number.
01:07
For example, decimal number one would command a combination of b and c.
01:15
And the second step involves constructing the truth table using the seven display input signals, decimal number and corresponding four -digit binary numbers.
01:29
The truth table for the decode design depends on the type of seven -segment display.
01:36
As we mentioned above that for a common cathode 7 segment display, the output of the decoder or the segment driver must be active high in order to glow that segment.
01:54
So the given figure have the truth table.
02:00
So here it is digit.
02:02
Here a b c d e sorry a b c d then small a small b small b small d e f and g so here digit will be here it is 0 1 2 3 4 5 6 7 8 and 9 and then here for a, it will be 0 ,000, 1 .11...
