sir app ke liye clonning karna easy hota hai .... but hamara notebook copy me clonning karne me jan chala jata hai🙃.....anyway thanks for this premiuim quality of lectures❤❤

VIDEO NOTES 1) Decoder has n input lines and less than or equal to 2^n output lines and an enable pin. 2) We have said less than equal to 2^n output because there can be some Don't Care conditions. 3) Decoder basically outputs the position of the input data on a truth table 4) Demux relation with Decoder (9:13) 5) For designing use the typical steps: make truth table, derive the minimized equation and then make the circuit. Eg 2x4, 4x16. If you add enable pin, E with expression for active high, E' with expression for active low (15:13) 6) For binary to octal decoder, we know that input will be binary and output will be octal. So there will be 8 output lines(octal is base 8) and so 3 input lines (2^3=8) (20:16) It will also follow the typical designing steps. 7) For BCD to Decimal decoder, we will only make 10 output lines instead of 16 because rest 6 will be don't care. However, we will write those don't cares in the truth table and equations. Now minimize all the equations using K-Map. (38:12). Then Finally design the circuit.

So deep and insightful explanation about use of don't cares 🙌🏻

Great Video🤯

You still watching and commenting! Keep it up bro! Good Luck

[@ChandanAkbarpuria]

One of the best explanation for decoder

[@sarth8065]

Last vala part bilkul nahi samjha. Why you have considered don't care as 1 and how did you know that exactly which o/p lines will be on?

[@ghostshadow4816]

Watch K-map videos of Sir, ur don't care concept will be clear why it is considered as 1. When A = 1 B = 0 C = 1 D = 0 Then, it's same as AB`CD` D2 = B`CD` D8 = AD` AB`CD` contains both minterms so 2 bulbs should glow but that's invalid due to the invalid input. Similary Try for 11, 12, 13, 13 and 15. You will understand. This doesn't happens when you take €(0,1,2,3,4,5,6,7,8,9)

at 49:15....what is minimum literal count.... please tell 🥺

[@Thakur_Abhays]

clarify your question ??

[@aditithakur9281]

@@Thakur_Abhays not sure , i just find that at both case bulb will glow so total number of literal could be 5 ... . .. although i don't know

[@Thakur_Abhays]

@@aditithakur9281 you are saying 5 because when we give input 1010 two bulbs glows D2 and D8 minterm for these respectively is B'CD' and AD'. But we don't care about how many bulbs are glowing in this case because input is wrong. Literal count for 10 (D10) is 2, you can determine it from kmap. Minterm will be AC or AD'

[@aditithakur9281]

@@Thakur_Abhays ac or ad logically means ac + ad' why to consider one minterm to calculate function D10
