#X text 71 367 This patch measures the spectrum of two-operator phase
|
|
modulation. The carrier frequency is initially six times the modulation
|
|
frequency \, but you can change it with the "carrier harmonic #" control.
|
|
Changing the index changes the relative strengths of the harmonics.
|
|
Past a certain index (which depends on the carrier frequency) the lower
|
|
sidebands begin to reflect about the left edge of the spectrum \, causing
|
|
complicated interference effects.;
