21. Assertion (A) : At room temperature, 
the fermi level in a p-type 
semiconductor lies nearer to 
the valence band whereas that 
in n-type semiconductor lies 
nearer to the conduction band. 
 Reason (R) : At room temperature, 
the p-type semiconductor has 
majority charge carrier are 
holes whereas the n-type 
semiconductor, the majority 
charge carriers are electrons.   
Paper-II 4  D-88-11 
22. Assertion (A) : Superposition 
theorem is a method of network 
analysis that permits 
considering the effects of each 
source independently.

permits the reduction of any two 
terminal linear ac network to 
one having a single voltage 
source and series impedance. 
 
23. Assertion (A) : A monostable 
multivibrator can be used to 
alter the pulse width of a 
repetitive pulse train. 
 Reason (R) : Monostable 
multivibrator has a single stable 
state. 
 
24. Assertion (A) : In Intel 8085, the 
lower byte of address and data 
are multiplexed.  
 Reason (R) : This helps limit the 
number of external pin 
terminals.

 Question Nos. 21 to 30 are Assertion 
and Reason type. Select your answers 
to these items using the codes given 
below and mark your answer sheet 
accordingly. 
 Codes : 
 (A) Both (A) and (R) are true and 
(R) is the correct explanation of 
(A). 
 (B) Both (A) and (R) are true but 
(R) is not correct explanation 
of (A). 
 (C) (A) is true but (R) is false. 
 (D) (A) is false but (R) is true. 
 
21. Assertion (A) : At room temperature, 
the fermi level in a p-type 
semiconductor lies nearer to 
the valence band whereas that 
in n-type semiconductor lies 
nearer to the conduction band. 
 Reason (R) : At room temperature, 
the p-type semiconductor has 
majority charge carrier are 
holes whereas the n-type 
semiconductor, the majority 
charge carriers are electrons.

22. Assertion (A) : Superposition 
theorem is a method of network 
analysis that permits 
considering the effects of each 
source independently. 
 Reason (R) : Thevenin’s theorem 
permits the reduction of any two 
terminal linear ac network to 
one having a single voltage 
source and series impedance. 
 
23. Assertion (A) : A monostable 
multivibrator can be used to 
alter the pulse width of a 
repetitive pulse train. 
 Reason (R) : Monostable 
multivibrator has a single stable 
state. 
 
24. Assertion (A) : In Intel 8085, the 
lower byte of address and data 
are multiplexed.  
 Reason (R) : This helps limit the 
number of external pin 
terminals. 
 
25. Assertion (A) : R-2R ladder type 
D/A converter has a higher 
speed of conversion than a 
weighted resistance D/A 
converter. 
 Reason (R) : R-2R ladder type 
D/A converter uses a smaller 
number of components than the 
weighted resistance D/A 
converter. 
 
26. Assertion (A) : The top down 
structured programming should 
be used for developing 
programmes. 
 Reason (R) : The top down 
structured programming 
methodology enables us to get 
readable and easily provable 
program. 
 
27. Assertion (A) : The port of root 
locus on the real axis is not 
dependent upon the poles and 
zeroes which are not on the real 
axis. 
 Reason (R) : Poles and zeros 
which are not on the real axis 
always occur in conjugate pairs. 
28. Assertion (A) : Master-Slave JK flip-
flop is free from race around 
condition. 
 Reason (R) : Master-Slave uses 
two J-K flip-flop. 
 
29. Assertion (A) : A demultiplexer 
cannot be used as a decoder. 
 Reason (R) : A demultiplexer 
selects one of many output 
whereas a decoder selects an 
output corresponding to the 
coded output. 
 
30. Assertion (A) : A processor can 
reference a memory stack 
without specifying an address. 
 Reason (R) : The address is 
always available and 
automatically updated in the 
stack pointer.
