Q:

What are the different Adder circuits you studied?

Answer

Adders are generally of five types:


1.Ripple Carry Adder:


The Ripple carry adder(RCA) consists of a building block named Half Adder(HA) which is cascaded to form a Full Adder(FA). These buildingblocks HAs and FAs are also the building blocks of all types of adders.The n full adders are cascaded to form n bit RCA.


The full adder has three input pins(input Ai,input Bi,carryin Ci) and two output pins(Sum and Ci+1).Its equations are:


Sum=Ai^Bi^Ci


Ci+1=Ai.Bi+Bi.Ci+Ai.Ci


 


2. Carry Lookahead Adder:


The Carry Lookahead Adder(CLA) reduces the delay as that in RCA. Let Gi=Ai.Bi, and Pi=Ai^Bi, then Ci+1=Gi+Pi.Ci.


The expressions for Sum and Ci+1 is then defined completely in terms of input pins rather wait for input carry to appear.


 


3. Carry Select Adder:


The carry select adder uses duplicate modules for each combination of input carry(i.e. 1 and 0).The multiplexers then select the appropriate sum and carry output according to the carry output of the preceding stages.


 


4. Carry Skip Adder:


The carry skip adder are as fast as carry lookahead adders which are the fastest adders but its spped decreases to about 20-30% if input operands are 64-bit or more. In these adders we divide the input bit stream into various blocks and make use of two observations:


-if each element of the two bit streams are unequal,i.e. Ai!=Bi than the carry input of the block is equal to the carry input.


-if each element of the two bit streams are equal,i.e. Ai=Bi than the carry input of the block is opposite of the carry input.


 


5. Carry Save Adder:


The carry save adder reduces the addition of three elements into addition of two elements,i.e. if you want sum of nine numbers it reduces it into sum of six numbers. In first step the sum of three numbers is calculated without bothering for the carry.During the second step only carry is calculated which is then added to the generated sum to give the required sum.

Q:

Name some situations in which a leader may fail. Tell me about a time when you fail as a leader?

Answer

Tips :


Occasionally some things go out of control of leaders such as the suitable skill pool in the organization, deadline, and the economic situation. The failure can happen if the employees are unconcerned and negative. In leadership interview questions, the interviewer wants to know your way in resolving the difficult situations, so you should concentrate on analyzing the failure and draw the experience from it. The way you used the difficulties to design the policies and trainings. Show your bravery to face with the failure and ready to recover and continue going on.

Q:

MONEX is associated with

A) Monetary experiment B) Lunar experiment
C) Montreal experiment D) Monsoon experiment
 
Answer & Explanation Answer: D) Monsoon experiment

Explanation:

Monsoon experiment is abbreviated as MONEX.

 

The Monsoon Experiment is the core of the GARP Monsoon Subprogramme, which is a major international effort to achieve a better understanding of the Planetary monsoon circulation, the major seasonal perturbation of the general circulation of the atmosphere and the influence of the annual cycle of precipitation associated with the monsoon on the agriculture of the many populous nations of the region.

 

Hence, MONEX is associated with The Monsoon Experiment.
