----------
syslist : list of LTI
List of linear input/output systems (single system is OK)

Hz: boolean
If True, the limits (first and last value) of the frequencies
are set to full decades in Hz so it fits plotting with logarithmic
scale in Hz otherwise in rad/s. Omega is always returned in rad/sec.
number_of_samples: int
Number of samples to generate
feature_periphery_decade: float
Defines how many decades shall be included in the frequency range on
both sides of features (poles, zeros).
Example: If there is a feature, e.g. a pole, at 1Hz and feature_periphery_decade=1.
then the range of frequencies shall span 0.1 .. 10 Hz.
The default value is read from config.bode_feature_periphery_decade.

Returns
-------
omega : array
Range of frequencies in rad/sec
number_of_samples: int
Number of samples to generate
