– overlapping frequency ranges or channels to different signals or to each user of a medium. A gap is left between each of these channels to ensure that the signal of one channel does not overlap with the signal from an adjacent one. because of scarcity of digital filters it was very difficult to filter closely packed adjacent channels. 2.Multicarrier modulation:- it is not convenient and efficient to transfer a high rate data stream through a channel, the signal is divided into a number of…

As you…

probable reasons for the Mayan civilization collapse and two authors, David Drew and Payson D. Sheets, have internal and outside factor of assumptions on possible explanations.

societies. The reasons Oxfam puts forward to explain this are well founded. Oxfam outlines the ways in which extreme wealth and inequality are destructive to the environment. The argument here is a little uncertain: While they do mention the growing scarcity of resources, and they do point to studies that show countries are better at reducing carbon emissions when they are more equal, their argument falls short because they neglect to mention that in fact one of the biggest threats the…
In defense of the survivors’ guilt arising from not helping the poor, he claimed that “the net result of conscience-stricken people giving up their unjustly held seats is the elimination of that sort of conscience from the lifeboat”. He defined guilty about one’s good luck as a type of conscience and the newcomer’s lack of guilt about the rich people’s loss as conscience drain; but the author deliberately omitted the morality of rich people’s indifference to the poor asking for help. Counting…

The “differences in culture and language as well as the scarcity of resources became the defining distinction of who gained access to economic opportunities; [and] race became a proxy for the cultural and language differences” within Compton’s Community (Straus 515). Compton’s public school system illustrated…

This excerpt changes that by looking at Frederick Douglass’ scrutiny of slavery and his condition. As I read the excerpt, I understood why one particular event was important to him and the comparison between the enslavers and criminals was so significant. I also contemplated on why he would much rather be an animal instead of a…
