Is changing the frequency of the carrier wave to match the amplitude of the signal is called frequency modulation?
more or less, yes
How are frequency and amplitude related?
They're not. The same amplitude can have high or low frequency, and the same frequency can have large or small amplitude.
Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
How the amplitude and the frequency of oscillator can be changed?
by pooing
Does changing the frequency change the amplitude?
In respect to what? But frequency is different than amplitude, so no.
Is changing the frequency of the carrier wave to match the amplitude of the signal is called frequency modulation?
more or less, yes
How does changing the amplitude change the frequency?
There's no connection between amplitude and frequency. Either one can change, and often does, with absolutely no effect on the other.
How do waves carry signals?
Waves can be varied (modulated) by either changing amplitude (amplitude modulation AM) or changing frequency (wavelength) (frequency modulation FM). The modulations are used to carry the information signal.
Comparison of amplitude modulation and frequency modulation?
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
Operation of a transformer?
Transforming a signal without changing its frequency.(amplitude can be changed)
What affect if any does frequency have on the amplitude of a wave?
The sound pressure amplitude tells about how loud the tone will be and the frequency (cycles per second) of the oscillation tells how high the sound of the tone will be. The amplitude gives the loudness of the tone: http://en.wikipedia.org/wiki/Loudness The frequency gives the pitch of the tone: http://en.wikipedia.org/wiki/Pitch_%28music%29
How are radio and television waves added to em waves?
by changing the amplitude or frequency of the radio waves.
How are frequency and amplitude related?
They're not. The same amplitude can have high or low frequency, and the same frequency can have large or small amplitude.
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
