1. What is the radio wave? Please explain it. Also, how can you convert the frequency to wavelength of a wave in free space? (You can show it by formula and any necessary data)
2. What are names of frequency bands between 300 Hz to 30 GHz? Please also show some of the application of some frequency bands.
3. A 2-MHz carrier is modulated by a music signal that has frequency components from 20 Hz to 4 kHz. Determine the range of frequencies generated for the upper and lower sidebands of AM signal.
4. An unmodulaed carrier is 300 Vp-p. Calculate %m when its maximum p-p value reaches 400, 500, and 600V of AM signal.
5. In an FM transmitter, the output is changing between 90.002 and 89.998 MHz 1800 times a second. The information signal amplitude is 2 V. Determine
the carrier frequency and information signal frequency. If the output deviation changes to between 90.001 and 89.999 MHz, calculate the information signal
amplitude.
