Multiple Channel Summing
The I and Q waveforms combine in the I/Q modulator to create an RF waveform. The magnitude of
the RF envelope is determined by the equation
, where the squaring of I and Q always results
in a positive value.
As shown in
Figure 3-
11, simultaneous positive and negative peaks in the I and Q waveforms do not
cancel each other, but combine to create an even greater peak.
