What is level of modulation

[jakin]

Hi,
I cannot picture 4-level modulation. Does that mean 1-level and 2-level and 3-level ,and the end is 4-level ? Please give me some definition.


Thanks in advances

ur question is nt clear rephrase it

 

[T.Engineer]

on which type of modulation do you mean.
there are many types of modulations for example : pulse position modulation, pulse amplitude modulation, BSK, FSK. So which one of these do you mean

Lets take ground level(0V) to be one level, you'll need 1/3V,2/3V and V, but thats the voltage that appears across the load, depending on your converter the way this is made possible will vary.

i think level modulation means PAM modulaion

It should be actually PAM only because as answwerd above voltage levels are measure of amplitude only.....
