_____________ is essentially a crude form of Amplitude shift keying.

_____________ is essentially a crude form of Amplitude shift keying. Correct Answer Digital intensity modulation

Many techniques have been developed to amplitude modulate an optical signal. Digital intensity modulation used in direct detection systems is essentially a crude form of ASK in which the received signal is detected using square law detector.

The following sentences form a paragraph. They are numbered a P, Q, R and S. These four parts are not given in their proper order. Read the sentences and choose the alternative that arranges them in a correct order. P. This has led to a fall in value of the foreign reserves and also faces frequent disturbance during the rise in crude oil prices. Q. India is dependent on imports of petroleum, where around 82 percent of its crude oil requirement is derived from the Middle East. R. The rising number of automobiles has also raised the increase in consumption, where the crude oil import volume amounted to approximately 217 million metric tons during the year 2018. S. In order to contain the rise, the government and other economic experts have raised the cause of the bio-fuel as a replacement for the crude oil.
A statement is given below in the question 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 following suggested courses of actions logically follow(s) for pursuing. Statement: Hindustan Unilever and Nestlé plan to selectively increase prices of their products to take into account higher crude oil and petrol costs, the rupee’s depreciation against the dollar and more expensive commodities such as wheat. If crude remains where it is and if the rupee has depreciated, of course, there are headwinds as far as costs are concerned. I. Nestlé India’s logistics providers are looking to renegotiate rates after record-high petrol and diesel prices. Nestlé declined to comment on when and by how much prices would increase.  II. Nestlé commented that HUL had dropped prices in November after the Goods & Services Tax was introduced last year and an increase in prices now would likely not hurt consumers.  III. Petrol prices have crossed Rs 90 a litre in Mumbai on increasing global prices of crude oil, of which India is a net importer, further impacted by the falling rupee. Crude derivatives, which are key inputs for FMCG companies, and petroleum derivatives used in packaging material including bottles and tubes, have also become more expensive.
The ratio of men and women in shift I workers is 1 : 3 and ratio between the women and men in shift II workers is 2 : 3. When both shift workers are present then ratio between the men and women is 23 : 27. Find the ratio between the men of shift II and shift I.

Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over million of years, these dead creatures form large deposits under sea­bed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.

The shift register shown in the figure is initially loaded with the bit pattern 1010. Subsequently, the shift register is clocked, and with each clock pulse the pattern gets shifted by a one-bit position to the right With each shift, the bit at the serial input is pushed to the leftmost position (MSB) After how many clock pulses will the content of the shift register become 1010 again?
