Assume an FM system has a frequency deviation of 10 kHz when the modulating signal has an amplitude of 4 Volts and a frequency of 2 kHz. Determine the frequency deviation if the modulating signal is (Hint: this info will give the modulator sensitivity (kHz/Volt):
a. Increased to 6 Volts
b. Changed to 5 KHz
c. Increased to 10 Volts and a frequency of 8 KHz
