HPCL model question paper for ECE branch

Hi buddy here I would like to know that from where I can obtain HPCL model question paper for ECE branch

[Raman Vij]

As you want to collect HPCL model question paper for ECE branch, so I want to inform you that syllabus of any PSU along with HPCL for any stream is more or less same as that of GATE exam so you can consult the syllabus of GATE for preparation of HPCL or any of the PSUs, that why here I am providing GATE ECE branch paper

1. A bulb in a staircase has two switches, one switch being at the ground floor
and the other one at the first floor. The bulb can be turned ON and also can
be turned OFF by any one of the switches irrespective of the state of the
other switch. The logic of switching of the bulb resembles
(A) an AND gate (B) an OR gate (C) an XOR gate (D) a NAND gate
Answer: (C)
Exp: (C)
Let Switches = 1 2 p , p
1 2 p , p Z(o / p)
OFF OFF OFF
OFF ON ON
ON OFF ON
ON ON OFF
From Truth Table, it can be verified that Ex-OR logic is implemented.
2. Consider a vector field ( ) A r

. The closed loop line integral A d l •

can be
expressed as
(A) ( ) A ds Ñ × •

over the closed surface bounded by the loop
(B) ( ) A dv Ñ •

over the closed volume bounded by the loop
(C) ( ) A dv Ñ •

over the open volume bounded by the loop
(D) ( ) A ds Ñ × •

over the closed surface bounded by the loop
Answer: (D)
Exp: (D)
Stoke’s Theorem: “ The Line Integral of a vector A around a closed path L is
equal to the integral of curl of A over the open surface S enclosed by the closed
path L”.
( ) \ = Ñ × A.dl A .ds
3. Two systems with impulse responses ( ) ( ) 1 2 h t and h t are connected in cascade.
Then the overall impulse response of the cascaded system is given by
(A) Product of ( ) ( ) 1 2 h t and h t
(B) Sum of ( ) ( ) 1 2 h t and h t
(C) Convolution of ( ) ( ) 1 2 h t and h t
(D) Subtraction of ( ) ( ) 2 1 h t from h t
