A microwave data link has been designed to operate at 110,000 symbols per second while encoding 14 bits per symbol. The receiving equipment requires at least a 50 dB signal to noise ratio in order to operate without significant error. which of the following are true:At least 55 kHz of bandwidth on the transmission channel are required for the attempted system. The data rate of the designed link will be 1.54 Mbps. If the actual signal to noise ratio is 100 dB, the system could support encoding as many as 17 bits per symbol. There is not enough information given to determine the minimum transmission power needed to make sure an acceptable power level arrives at the receiver. Exactly 16,384 symbols are needed to support 14 bits per symbol. If the background noise at the receiver is -50 dBm, the receive power will need to be at least 0 dBm.

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words. size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words. size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }

When converting the erd to a table design, how should you handle the assignedto relationship? (be sure to include a discussion of primary keys, foreign keys, and tables in your answer.)11. true/false projectid will be a foreign key in the employees table to reflect the “manages” relationship.12. after converting the erd to a table design, what fields will be present in the contracts
