1. Show how a modem would encode the 5-bit binary sequence 11001 onto an analog carrier bya. Modifying its amplitude (the height of the carrier wave)b. Modifying its frequency (the number of waves per second)2. A modem can also modify the phase of a carrier wave to encode binary data. Find out what the phase of a signal is and determine how it can be modified so that it can encode the same 5-bit signal 11001 used in Exercise 1.3. Determine the total time it takes to transmit an uncompressed gray scale image (with 8 bits/pixel) from a screen with a resolution of 1280 x 840 pixels using each of the following media:a. A 56 Kbps modemb. A 1.5 Mbps DSL linec. A 100Mbps Ethernet link
