NOR Gate as Universal Gate

Then first time you wasn't listen the lecture clearly......

[@sudarsan.r5985]

Then you should try taking notes on the first go itself

[@gurdeepdhillon5087]

Hw Problm 1 explained properly😊: We use complement of A and B asitis as inputs for nor gate. And for other we use complement of C and D asitis as input for other nor gate. We use output of both nor gates as input of one more not gate and hence we get required result. :D

[@gurdeepdhillon5087]

So, in total we use 5 nor gates.

What about the second question?

[@nishupanwar7442]

1) 5 gates 2) 4 gates (if we first take dual of expression and then solve)

[@ConfidencePoint1]

How answer of 1st question is 5 ?

[@prithvi_krishna]

Is the second one a self dual function ?? I don't think so. So it's not possible with 4 nor gates. Normal simplification leads to 7 nor gates.

[@nandhinik.s720]

U r right.. It is self dual.... But how you combine (ab) and (c. d') .U need to put one extra gate to get the output expression. .It will be an OR gate.... But here is the condition we must only use nor gate ....so in this case there is no other way to get the output . So we require 7 gates to get the output....

[@bulliraju5439]

1)correct 2) 7 gates

@@MrPotaatooo There were total 9 nor gates used in answer of first question and 4 of them were redundant as they were serving as not gates and eliminating them doesn't effect the output. So the answer is 9-4 which is 5.

[@manojraju4333]

Answer:A+B'

[@somureddy9579]

Bro it's distributive law a+(bc)=(a+b).(a+c)

[@ashrafabdelrahman1779]

during driving 5.XNOR === how did you drive (A+(A+B)').(B+(A+B)') to (A+B)' +AB ?

[@RazorM97]

by using the distributive propriety of addition x1 + (x2 * x3) = (x1 + x2)(x1 + x3) (A+B) is a common term for both, so it's like x1

[@stanleyvictor6464]

1: You need 5 2: You need 3...... not 7 NAND gates because the 4 inverters are redundant (X&Y) to one NAND and (W&Z) to another NAND and finally a NAND which has outputs of the 2 NANDS used earlier as i/p.

why mostly NAND gates are to be used in layout designing?

u should read about CMOS logic circuit, in NAND gates, it uses 4 transistor only for each gate, and it will be efficient to apply it on TTL IC 7400 series (common uses for this chapter) its not present in this video btw, cmiiw
