pypho_optfi.__init__(glova, Df, B, filtype, alpha, loss)

Instantiation and parameter setting.

Parameter Type Description
glova instance Global parameters
Df float Frequency deviation of the signal in GHz.
Default value is 0 GHz.
B float Filter bandwidth in GHz.
Default value is 100 GHz.
filtype string Defines the filter curve.
Default value is 'gauss'
Available filter curves 'gauss', 'rect', 'cosrolloff', 'gaussrolloff'.
alpha float Defines the alpha coefficicent for 'cosrolloff', 'gaussrolloff'.
Default value is 0.25.
loss float Defines the loss in dB of the filter curve at it's maximum.
Default value is 0.0 dB.
