# Frequency modulation

A sinusodial carrier wave has amplitude 12 volts and frequency 600 kHz.
The frequency of the carrier wave changes by 25 kHz per volt.
The carrier wave is to be used for the transmission of a signal of frequency 3 kHz and amplitude 2 volts.

For the frequency modulated carrier wave, state

1) the amplitude
2) the maximum frequency
3) the minimum frequency
4) the number of times per second that the frequency of the carrier wave changes from the maximum to minimum and then back to maximum value.

f=1/T

1) 12volts i belive since carrier wave doesnt change amplitude in frequency modulation
2) I believe it should occur when the information signal has maximum displacement b/c disp of the signal is varying in synchrony with frequency. But i donot know how to fine it

3)Maybe at minimum disp of signal.
4)No idea at all.
