Visualization & Results
• Annotations
– Add text and variable values – For 2D and 3D plots – Use coordinates for positioning
• •
Smith plots in the RF Module Octave and 1/3rd octave plots in the Acoustics Module
– Ability to solve the equations
• Caveat: Slow computers and specialized software needed to solve just a few simple equations
