Midterm 1.Chapter 3, Problem 4To achieve 75 percent modulation of a carrier of Vc-50V, what amplitude of the modulating signal Vm is needed?2.Chapter 3, Problem 14A ham transmitter has a carrier power of 750 W. How much power is added to the signal when the transmitter is 100 percent modulated?

3.Chapter 4, Critical Thinking question 3An SSB signal is generated by modulating a 5-MHz carrier with a 400-Hz sine tone. At the receiver, the carrier is reinserted during demodulation, but its frequency is 5.00015 MHz rather than exactly 5 MHz.  How does this affect the recovered signal?How would a voice signal be affected by a carrier that is not exactly the same as theoriginal?

4.Chapter 5, Problem 4For a single-frequency sine wave modulating signal of 3kHz with a carrier frequency of 36MHz, what is the spacing between sidebands?
