Chapter 4 155
Basic Digital Operation
Using Waveform Clipping
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 4-18, simultaneous positive and negative peaks in the I and Q waveforms do not cancel
each other, but combine to create an even greater peak.
