Constant envelope modulation techniques occupy ______ bandwidth than linear modulation schemes.

Constant envelope modulation techniques occupy ______ bandwidth than linear modulation schemes. Correct Answer Larger

Constant envelope modulation technique occupies a larger bandwidth than linear modulation technique. It is one of the disadvantage of constant envelope modulation. It is not well suited where bandwidth efficiency is more important than power efficiency.

The question below consists of a set of labelled sentences. These sentences, when properly sequenced form a coherent paragraph. Select the most logical order of sentences from among the options. P: About 30 new hydro projects are now under execution with an installed capacity of 5,600 MW. Q: However, with the rapid increase in demand for power, a higher priority was given to the pithead super thermal power stations as their gestation period was smaller than that of the hydel schemes. R: Many projects were taken up for execution after independence and at one time (1962-63), the capacity contribution from hydro schemes was equal to thermal schemes. S: The first hydro generating unit in India was commissioned in Darjeeling (W.Bengal) in 1897.

A man in his deathbed fixed all his savings for his 3 children in 3 different schemes in such a way that each scheme will pay the respective child at their age of 18. His son, who is 15 years old gets 40%, elder daughter, who is 14 years old got 35% and younger daughter, who is 12 years old got the rest. If all of them got the same interest at their age of 18, what is the ratio of the rate of interest of those 3 schemes? (Assume all the schemes pay in simple interest)
An equal sum is invested in two different schemes. One scheme gives simple interest and the other gives compound interest (annual compounding). The sum of interest obtained after 2 years from both the schemes is Rs. 2961. If both schemes have 23% per annum interest rate, then what is the first year interest (in Rs.) of simple interest scheme?
