Multiplexer Selection Lines (in Hindi)

Consider  a 4-to-1 multiplexer  with  two  select lines  S1 and  S0, given below diagram in lesson 

The minimal  sum-of-products  form of  the Boolean expression  for  the output  F of  the multiplexer  is (A)  P’Q  + QR’  +  PQ’R (B)  P’Q  +  P’QR’  +  PQR’  + PQ’R (C)  P’QR  +  P’QR’  +  QR’  + PQ’R (D)  PQR’

4-to-1 Multiplexer Solution (in Hindi )

The  output  of  the below  multiplexer  circuit  can  be  represented  by 
1.AB+BC'+C'A+B'C''
 2.A⊕B⊕C
 3.A⊕B 
4.A'B'C+A'BC'+AB'C'

Output of Multiplexer (in Hindi )

Consider  the circuit  shown  below (in lesson).  The  output  of a  2:1  Mux is given  by the function  (ac’  +  bc). 
Which  of the  following  is  true? (A)  f =  x1’+  x1x 
(B)  f  = x1’x2 +  x1x2′ 
(C)  f =  x1x2  +  x1’x2′ 
(D)  f =  x1 +  x2′

The Output of a 2:1 Mux (in Hindi )

The  circuit  shown  below  implements a  2-input  NOR  gate  using  two  2−4  MUX (control signal  1  selects the  upper  input).  What are  the values  of signals    x,y  and  z? 
1.1,0,B 
2.1,0,A 
3.0,1,B 
4.0,1,A

Input NOR gate using two 2−4 MUX (in Hindi)

The following  circuit  implements a two-input  AND  gate using  two  2-1 multiplexers. What are  the values  of  X1,X2,X3? 1.X1=b,X2=0,X3=a 2.X1=b,X2=1,X3=b 3.X1=a,X2=b,X3=1 4.X1=a,X2=0,X3=b

A two-input AND gate using two 2-1 multiplexers(in Hindi)

Consider the two cascaded 2-to-1 multiplexers as shown in the figure.                                                                                                                         The minimal sum of products form of the output X ?????

Two cascaded 2-to-1 multiplexers find minimal SOP (in Hindi)

For a  binary half  adder having two  inputs  A and  B  the  correct  set of logical  expressions  the output

Binary half adder output and sum values (in Hindi )
