a.Agent X and Agent Y are two spies who want to transmit a secret message to their headquarters. In order to ensure secrecy, half of this message is to be transmitted in Urdu by Agent x while the other half in Pashto by Agent Y Both halves when decoded together at the headquarters can convey the complete information and therefore must be sent in a single transmission

They have an AM transmitter but it has one problem that it can only transmit one carrier frequency. How can they simultaneously transmit both messages using this AM transmitter?

b. A radio transmitter TX1 is using amplitude modulation with maximum bandwidth of 10 kHz Due to some technical issue, the amplitude modulator stops working Technicians found out that it will take at least two days to repair the modulator. They have a frequency modulator and they want to use it to transmit the information using frequency modulation. Is it possible with the given constraints? Why or

why not?

An agent chooses between two goods, x and y, with prices px and py, respectively. She has an income I and her preferences are represented by the utility function U (x, y) = lnx + y. A. Suppose that I = 100, px = 2 and py=1. How much of good x and y will the agent choose? B. If the price of good x rises to px=4, with income and the price of good y remaining the same, what...

A message consists of 8,000,000 bytes. The sender’s network adapter can transmit at a rate of 100,000 bytes per a second. The receiver’s network adapter can receive 40,000 bytes per second.   It takes 20 ms for data to move across the network.   Assuming no data is lost on the way, how long does it take for the message to read in by the receiver?

Assignment in C: prompt the user to enter secret message that is terminated by presding Enter. You can assume that the the length of this message will be less than 100 characters. You will then parae this message, character by character, converting them to lower case, and find corresponding characters in the words found in the key text word array. Once a character match is found, you will write the index of the word and the index of the character...
