CHAPTER 7 1. The ability of a receiver to choose a desired signal frequency while rejecting closely adjacent signal frequencies is known as selectivity. 2. Decreasing the Q of a resonant circuit causes its bandwidth to increase. 3. Good selectivity usually means narrow bandwidth. 4. True. A tuned circuit can provide voltage gain. 5. Cascading tuned circuits cause the selectivity to increase. 6. If the selectivity of a tuned circuit is too sharp‚ the sidebands of the received signal

1. Which of the following statements is true? a. The concept of defense-in-depth reflects the fact that security involves the use of a few sophisticated technical controls. (Incorrect. The concept of defense-in-depth is based on the idea that‚ given enough time and resources‚ any single control‚ no matter how sophisticated‚ can be overcome—therefore‚ the use of redundant‚ overlapping controls maximizes security.) b. Information security is necessary for protecting confidentiality‚ privacy‚ integrity

AODV has pooled properties of both DSR and DSDV. It uses route discovery process for sustaining route information through the basis of routing table. It is a reactive protocol as it doesn’t need to establish or maintain routes to nodes that are not involved in the communication. AODV handles route discovery process with Route Request (RREQ) messages to broadcast to neighbour nodes. The message floods through the network till the desired destination is reached. Sequence number guarantees the loop

Unit 3 Writing Assignment - Survey of the sciences Navigation Well pigeons and sea turtles are not the only creatures on this Earth to use a magnetic compass. But I found that sea turtles use inclination angle and intensity to follow certain routes in the ocean‚ they call these routes gyres. The gyre is known to be warm and have lots of food‚ but where the gyre is cold there is less food and turtles that follow these routes tend to die. Also a lot of these creatures tend to have a substance in

This depends on whether they have a wireless router or wired‚ if they have a wireless router then some internet ready televisions have wireless ability. Either way would work though running an Ethernet cable from the router into the back of the television would give the internet connect that is needed. Looking at the VoIP (Voice over IP) I would suggest Vonage as the service carrier for phone. The phone adapter and software needed for the VoIP is normally included with the purchase of Vonage phone
