Very clearly explained modulations, particularly for QAM.

My 15 colleagues couldn't explain me how it exactly works. Thank you very much. Now i can explain it for them.

Thank you so mucccccccc, you are f amazing goddess!!! if you just knew how many videos I have been watching to understand this and finally you just simplified and being able to explain to someone who is new and is not engineer , yet at least , thank youuuuuuuu

I have come across a different explanation of QAM where 2 waves are used (one sine wave and one Cosine wave - the Q comes from these being Pi/2 out of phase) and the points on the grid are the amplitudes of the 2 waves. I think there is BPSK where the amplitude changes from positive to negative).My question is, are there 2 versions of QAM - one using one wave and another using 2 waves?
@richardphillips24053 жыл бұрын
Great video. I am trying to figure out the waveforms. Would a 01 be created with a sine wave that has traveled 45 degrees at the beginning of the symbol period, a 11 be created by a sine wave that has traveled 135 degrees at the beginning of the beginning of the symbol period, a 10 by a sine wave that has traveled 225 degrees at the beginning of the symbol period, and a 00 being created by a sine wave that has traveled 315 degrees at the beginning of the symbol period?

must of new devices have many internal anttena so there is 2 to 3 signal handling in the same time and also the fade signal is handling
