Problem A signal has a fundamental frequency of 156250KHz. What is its period? Problem 2 A digital signaling system is required to operate at 56000bps. If a signal element encodes 4 bits values, what is the minimum required bandwidth of a noiseless channel? Problem 3 Given a channel with an intended capacity of 100Mbps, and a bandwidth of 10MHz. What signal to noise ratio is required to achieve that capacity? Problem 4 Consider a 8000 byte message transmission in a network. Suppose the message is broken in packets of 500 bytes with an additional 10 bytes header per packet. If the packets must be transmitted through 3 switches (sender +3 switches + receiver) at a data rate of 102Mbps. What is the total transmission time for the entire message
