1. What is the bandwidth of an AM signal whose carrier is 2.1 MHz modulated by a 1.5-kHz square wave with significant harmonics up to the fifth? Calculate all the upper and lower sidebands produced. 2. State how the frequency of a carrier varies in a PM system when the modulating signal amplitude and frequency change. 3.The maximum deviation of an FM carrier with a 2.5 kHz signal is 4 kHz. What is the deviation ratio? 4. Use Carson
