Questions around the NTSC TV signal
The NTSC television signal format uses frequency modulation of a 4.5 MHz sub carrier to attach the TV audio signal to the baseband video signal which extends from 0 Hz to 4.2 MHz.
The maximum frequency of the baseband audio signal is 10 KHz and the bandwidth allocated to the FM audio signal is 100 kHz.
a. What is the peak frequency deviation of the FM signal?
b. What is the FM improvement in dB?
c. Give two advantages of FM over DSB-LC AM in this application
d. Is the FM signal wideband or narrowband FM?
