It is positive and negative signal in the frequency of wave form, the voltage of amplitude modulation, that carriers the signal of frequency.In the process of graph showing result ...
the modulation system is of FM

QAM is a combination of phase modulation & amplitude modulation.

how can you draw a coordinate graph using feet and meters
Modulation
There are a great many different ways in which you could draw a reaction rate graph. You could draw a bar graph for example.
FM means frequency modulation AM means amplitude modulation
Graph
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.
When people are taught trigenometry in school it is usually just for finding the angles of a triangle. But the sine and cosine functions are actually waves if you were to draw them on a graph. Acoustics is sound waves, and by mapping sound waves into trigonometric waves we can do calculations on them like addition.
Modulation
you draw a circle and then put it on a graph
