[amp_mcq option1=”Spectral density” option2=”Bandwidth efficiency” option3=”Power density” option4=”Power efficiency” correct=”option1″]<\/p>\n
The correct answer is A. Spectral density<\/strong>.<\/p>\n Spectral density is a measure of the power or energy per unit bandwidth of a signal. It is often used to characterize the noise in a communication system.<\/p>\n Bandwidth efficiency is a measure of how well a communication system uses the available bandwidth. It is often expressed as the ratio of the throughput data rate to the bandwidth of the system.<\/p>\n Power density is a measure of the power per unit area of a signal. It is often used to characterize the strength of a radio signal.<\/p>\n Power efficiency is a measure of how much power a communication system uses to transmit a given amount of data. It is often expressed as the ratio of the throughput data rate to the power consumption of the system.<\/p>\n Spectral density is the most relevant measure for the given question because it is the only measure that is directly related to the throughput data rate. The other measures are related to other aspects of communication systems, such as noise and power consumption.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Spectral density” option2=”Bandwidth efficiency” option3=”Power density” option4=”Power efficiency” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[199],"tags":[],"class_list":["post-54978","post","type-post","status-publish","format-standard","hentry","category-wireless-communication","no-featured-image-padding"],"yoast_head":"\n
