setValues( rippleFactor=0, order=2, operation=NONE, halt=0, limit=None, invariant=NONE, )[源代码]¶

This method modifies the Chebyshev2Filter object.

参数:¶

rippleFactor=0¶: A Float specifying the amount of allowable ripple in the filter. Possible values are non-negative numbers less than 1. The default value is 0.025.
order=2¶: An Int specifying the highest power of the filter transfer function. Possible values are non-negative numbers less than or equal to 20. Order is not available for OperatorFilter. The default value is 2.
operation=NONE¶: A SymbolicConstant specifying the filter operator. Possible values are NONE, MIN, MAX, and ABS. The default value is NONE.
halt=0¶: A Boolean specifying whether to stop the analysis if the specified limit is reached. The default value is OFF.
limit=None¶: None or a Float specifying the threshold limit, an upper or lower bound for output values depending on the operation, or a bound for stopping the analysis when Halt is used. The default value is None.
invariant=NONE¶: A SymbolicConstant specifying the invariant to which filtering is applied. Possible values are NONE, FIRST, and SECOND. The default value is NONE.
