Fast-look-ahead carry circuits found in most 4-bit full-adder circuits which ___________ Correct Answer Reduce propagation delay

A carry-lookahead adder (CLA) is a type of adder used in digital logic. A carry-lookahead adder improves speed by reducing the amount of time required to determine carry bits. It reduces the propagation delay by making the hardware more complex. The ripple carry design is converted in such a way that carry over a group of bits of the adder becomes 2-level logic.

The addition of two binary variables A and B results in a SUM and a CARRY output. Consider the following expressions for SUM and CARRY outputs. (a) SUM \( = A \cdot B + \;\overline {AB} \) (b) SUM = A⋅B̅ + A̅ ⋅ B (c) CARRY = A⋅B (d) CARRY = A + B Which of the following expressions are correct?
A candidate takes a test and attempts all the 100 questions in it. While any correct answer fetches 1 mark, the wrong answers are penalised as follows; one-tenth of the questions carry 1/10 negative marks each, one-fifth of the questions carry 1/5 negative marks each and the rest of the questions carry 1⁄2 a negative mark each. Unattempted questions carry no marks. What is the difference between the maximum and the minimum marks that he can score? 
Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count there by reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification.   Consider the following digital circuits. 1. Multiplexers 2. Read Only Memories 3. D-latch 4. Circuit as shown in figure below Which of these come under the class of combinational circuits?
Five sources of energy – oil, coal, gas, water and wind are scheduled to be found at 5 different times of a day – 2 pm, 3 pm, 5 pm, 6 pm and 9 pm. Wind is not scheduled to be found at 3 pm. Oil is scheduled to be found at time between 3 pm and 6 pm. Coal is scheduled to be found before 5 pm. Gas is scheduled at time after 5 pm. Water is found to be available only after 6 pm. Which source of energy is to be found at time before 3 pm?
In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested courses of action logically follow(s) for pursuing. Statement: Soon you would not need to carry original copies of all vehicle papers like driving licence, vehicle registration certificate, insurance, pollution certificate or the permits issued to commercial vehicles with you. According to a ToI report, the Centre plans to amend Motor Vehicles Rules to make it legal for any citizen to carry digital vehicle documents and simultaneously making it compulsory for traffic police to accept digital version of documents. This means that you would not have to carry physical papers in your vehicle as digital copies of the certificates would be valid.  Courses of action: I. The ministry has proposed installation of FASTags on the front windscreens. FASTag is a device that uses radio frequency identification (RFID) technology for making toll payments directly from the user account.  II. To avail the facility, one has to store all the vehicle documents on the government's cloud-based service DigiLocker and when asked he/she can simply display the stored certificates on a smartphone or any other digital devices. These digital copies can be shared with other departments as identity and address proof.  III. The government has increased the maximum load carrying capacity of heavy vehicles, including trucks, by 20-25 per cent besides scrapping the mandatory annual renewal of fitness certificates for freight carriers. Fitness certificates for trucks would now be renewed in every two years not annually.  Which of the following course/courses of action can be said to be said to be a rudimentary course/courses of action?
There are three boats B1, B2 and B3 working together they carry 60 people in each trip. One day on early morning B1 carried 50 people in few trips alone. When it stopped carrying the passengers B2 and B3 started carrying the people together. It took a total of 10 trips to carry 300 people by B1, B2 and B3. It is known that each day on an average 300 people cross the river using only one of the 3 boats B1, B2 and B3. How many trips it would take to B1, to carry 150 passengers alone?
