What is Decoder?
The Decoder is the logic circuit that has N inputs and M outputs. And depending on the input combination of N inputs, only one of the M outputs is high.
Applications of Decoder:
1) Coder Conversion
2) Address Decoding in Processor
3) Generating the control signals for peripheral devices
4) Implementing logic circuits (e.g Full adder, parity generator, etc.)
In this video, the logic circuit of 3 to 8 decoder and BCD to decimal Decoder is explained in detail. And at the later part of the video, how to design 5 to 32 decoder using 3 to 8 Decoders is also explained.
This video will be helpful to all the students of science and engineering in understanding the basics of the decoder and its different applications.

You have no idea how helpful yor lessons are. I passed 'Introduction to Digital Systems' part thanks to you. Thank you
hope i would pass my computer systems 🥺🥺🥺
Covered all the concepts in one video...Very Thanks sir for this amazing lecture!!!
Clear explanation covering all the topics!
Great video, so helpful and organised
Superb and crisp explaination.
very helpful video, thank you !!
Great work!! I believe it has taken tons of time to create such content.
Best explanation 👌🏻👍🏻
Hello sir, your way of explanation and demonstration is Very much understandable for us, thank you sir, 🙂🙏
Sir, could you please make a series on COMPUTER ORGANIZATION for BSC PHYSICS students?
Thankyou so much for this detailed and good explanation. Watching your video for my exams! Slay.
Thanks a ton sir :) You saved me!
love you dude...helped me lot
thank you
we really appreciate you
Well explained ❤👏
wow! bro. Thank You so much for this :)
Thank you so much it helped a lot sir🎉
Great video
Supervd Way of explanation ...
My DLD exam is after 2 hours I wish I had discovered your channel before 🥺
Thank you so much🎉❤
👍 well done
18:20
the circuit we are discussing is parity checker not generator.
Superb video
V. Nice 👌👌 👌 👍
thanks sir
perfect
Is there anywhere I can send you an image that I need decoding for a new update on a game I'm struggling?
4:58 so, this is similar to Demultiplexer (DEMUX) right?
Understood.
For
n-variable function implementation using decoder, what should be the size of the decoder?
For n-variable function, we require n to 2^n decoder.
For example, for 3 variable function, we require 3 to 8 decoder.
Bestttt
CHICLAYO PERU 🇵🇪 💪 💪
10:09 will watch later
whats the difference between a decoder and a de multiplexer
In case of the decoder, based on the input code to the decoder, specific output will become high. For example, if the input code is 100, then 4th output line will become high.
In case of the Demultiplexer, the multiplexed data is the input. Based on the selection inputs, the input data will appear at the specific output line.
In Demultiplexer video, I have explained that how decoder can be used as a Demultiplexer.
Here is the link: ua-cam.com/video/eeWHM3zzK3M/v-deo.html&si=0B2BJcoQycOsZR_H
4:10 Shouldn't the memory 2 become high?
00 - Memory-1, 01- Memory -2, 10- Memory-3 and 11- Memory 4.
Therefore, memory 3 will get selected. The memory names (1 ,2 ,3 and 4) and their connection to decoder are not decimal equivalent of A9 and A8 bits.
I hope, it will clear your doubt.
14:41 how about if A3 and A4 are both high ?
When both A3 and A4 are high, then the last decoder will get selected. ( the fourth one)
@@ALLABOUTELECTRONICS I get it now thank you sir
Great video and well explained.
In 13:14 please how can I draw the truth table and logic circuit to the decoders?
The truth table of 3 to 8 decoder is shown at 6:04. And the logic circuit is shown at 6:09.
@@ALLABOUTELECTRONICS I understand that part already. I am just confused on how I will draw the truth table and logic circuit to the 4 to 16 decoder using 3 to 8 decoder
@@Sire_Presh You need to extend the truth table of 3 to 8 decoder. Similar to 3 to 8 decoder, in case of 4 to 16 decoder, you will have 16 outputs. About the circuit diagram, as I have shown in the schematic, you will require to draw two 3 to 8 decoder circuits and connect the pins according to the schematic. Just try it once you will get it.
@@ALLABOUTELECTRONICS Thank you very much. I've got it. I even attempted 5 to 32 decoder using 3 to 8 decoder and 2 to 4 decoder for the enable input. Did them successfully
This looks helpful with the animations but so hard to understand what he is saying if your not Hindi or whatever
Because most of the students watching from tamilnadu bro....🙃

At 7:23 I think the truth table which he has written is incorrect, he has written the values in reverse order. For eg for D1=1 we should giving the value from bottom C=0;B=0 and A=1, but he has done it in reverse order. Correct me if iam wrong.
A is MSB and C is the LSB. And the same is also shown in the truth table. That is why when C is 1 and A = B =0, then D1 =1. I hope, it will clear your doubt.
@@ALLABOUTELECTRONICS understood, thanks for the reply
In 16:27 why A2=0? I cannot understand this sir. Please explain it😊
Since we are constructing 5 to 32 decoder, so it will have 5 inputs. ( A4, A3, A2,A1, A0). A0, A1 and A2 inputs of the decoder are given to four 3x8 decoder, while A3 and A4 are given to fifth 3 x 8 decoder to select any one of them. Now here since we are not using the A2 input of the 5th decoder(because we are using it as 2x 4 decoder), so it is connected to 0. I hope, it will clear your doubt.
14:03 the image is wrong ig. the inputs names are in incorrect order
The input names for each decoder are according to their individual inputs. That is why the input to each 3 to 8 decoder is from A0 to A2 followed by Enable input.
Sir please hindi english mixx padhaiye
Sir hindi main hota to jayada acha samaj main aata
please add subtitle because your accent is very bad, I cannot understand what you are saying. Develop your accent or you do not have to speak english.
Subtitles are already been added. You may turn it on in the video settings.
abey shut ur as* up man. sir's accent is alright and his voice is soothing. get some good quality earphones blud.
Superb video
