The received signal-to-noise ratio is the ratio of the power of the desired signal to the power of the noise. The error probability is the probability that a bit is received in error. The bandwidth requirement is the range of frequencies that are required to transmit the signal.<\/p>\n<p>In general, we want to design a communication system with a high transmission rate, a high received signal-to-noise ratio, a low error probability, and a small bandwidth requirement. However, these parameters are often in conflict with each other. For example, increasing the transmission rate will typically require a higher bandwidth requirement.<\/p>\n<p>In practice, we need to find a compromise between these parameters that meets the specific needs of the application. For example, if we are designing a communication system for a high-speed data link, we will want to maximize the transmission rate. However, if we are designing a communication system for a low-power sensor network, we will want to minimize the power consumption, which may require us to reduce the transmission rate.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li><strong>1. Transmission rate<\/strong> is the maximum number of bits that can be transmitted per second. A higher transmission rate means that more information can be transmitted in a given amount of time. However, a higher transmission rate also requires a higher bandwidth requirement.<\/li>\n<li><strong>2. Received signal-to-noise ratio<\/strong> is the ratio of the power of the desired signal to the power of the noise. A higher received signal-to-noise ratio means that the signal is less likely to be corrupted by noise. However, a higher received signal-to-noise ratio also requires a higher power level.<\/li>\n<li><strong>3. Error probability<\/strong> is the probability that a bit is received in error. A lower error probability means that the data is more likely to be received correctly. However, a lower error probability also requires a higher transmission rate and\/or a higher received signal-to-noise ratio.<\/li>\n<li><strong>4. Bandwidth requirement<\/strong> is the range of frequencies that are required to transmit the signal. A higher bandwidth requirement means that more frequencies are required, which can lead to increased interference and power consumption.<\/li>\n<\/ul>\n<p>In conclusion, the correct answer is <strong>C. 1 and 3<\/strong>. We want to design a communication system with a high transmission rate and a low error probability. However, these parameters are often in conflict with each other. In practice, we need to find a compromise between these parameters that meets the specific needs of the application.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;1 and 2&#8243; option2=&#8221;3 and 4&#8243; option3=&#8221;1 and 3&#8243; option4=&#8221;2 and 4&#8243; correct=&#8221;option3&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[685],"tags":[],"class_list":["post-19540","post","type-post","status-publish","format-standard","hentry","category-information-theory-and-coding","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>For designing a communication system, which among the following parameters should be maximum? 1.
