74148 Datasheet:

Priority Encoder:
In Priority Encoder, unlike the normal Binary Encoder, each input has assigned a priority.
When more than one inputs are high, then the encoder gives the output corresponding to the input which has a higher priority. In this video, the working of 4 to 2 and, 8 to 3 Priority Encoder is explained using the truth table. And based on the truth table, how to design the logic circuit of the Priority Encoder is also explained in detail.
Finally, with the help of the Simulation of the Logic Circuit (of 8 to 3 Priority Encoder), the working is explained.

This video will be helpful to all the students of science and engineering in understanding the Priority Encoder.

17:19 you can take *D4'* common and after that you'll get *D3 + D3'•D2•D1* inside the bracket which is equivalent to *D3 + D2•D1*, now if u multiply the D4' back to these terms you'll get exactly the same term as before except the missing D3' which got eliminated, so the final result is:
*D7 + D6'•(D5 + D4'•D3 + D4'•D2'•D1), *
must do this step! It's efficient!

At 7:05 u taught that A+A bar= 1 .that is, in 4 to 2 line encoder. But in 13:34 that means in logic expression of 8 to 3 line u taught that A+ A bar= A itself. Clear tht doubt plz

Sir in 8:3 priority encoder diagram first 2 and last inverter's output is not connected to any where so can we remove these from ckt

At 7:05, u taught that A+Abar = 1 i.e; in 4 yo 2 libe encoder, but in 13:34 u taught that A+A bar= 1
