I realy enjoy from watching your video i was like you i saw 50 video and content in internet but now i found what is modulations.👌

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?

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?
