1.
1st, calculate the wavelength of a 950KHz carrier signal & 2nd true or false: the frequency
modulation means that the carrier frequency increases and decreases according the rise and fall
of the amplitude of modulation signal.
Solution
formula for walaelnght calculation is = c / f = c · T f = c /
answer 2- frequency modulation ( FM ) is the encoding of information in a carrier wave by
varying theinstantaneous frequency of the wave. This contrasts with amplitude modulation, in
which the amplitude of the carrier wave varies, while the frequency remains constant.
So here your statement is false because of above statement.
the modulation of a radio or other wave by variation of its frequency, especially to carry an audio
signal.
When rounding the speed of light c to 300,000,000 m/s you get:
