Magnitudes (dB)

Magnitude values for one or more lower singular value bound segments, specified in
decibels.

Specify the corresponding frequencies in Frequencies (rad/sec) on page 16-310.

Settings

Default []

Must be specified as start and end magnitudes:

• Finite numbers for a single bound with one edge


• Matrix of finite numbers for a single bound with multiple edges

For example, type [0 0; 10 10] for two edges with magnitudes [0 0] and [10 10].

• Cell array of matrices with finite numbers for multiple bounds

Tips

• To assert that magnitudes are satisfied, select both Include lower singular value
  bound in assertion on page 16-308 and Enable assertion on page 16-315.


• You can add or modify magnitudes from the plot window:
  
  
  • To add new magnitudes, right-click the plot, and select Bounds > New Bound.
    Select Lower gain limit in Design requirement type, and specify the
    magnitudes in the Magnitude column. Specify the corresponding frequencies in
    the Frequency column.
