 Reporter:  Brett_McS     |       Owner:  somebody
     Type:  defect        |      Status:  new     
 Priority:  normal        |   Milestone:          
Component:  scipy.signal  |     Version:  0.5.2   
 Severity:  normal        |    Keywords:          
--------------------------+-------------------------------------------------
 In function firwin of filter_design.py (signal) the return line (1542) is
   return h / sum(h,axis=0)
 which incorrectly calls the standard Python sum function (an error is
 flagged as the standard sum has no axis keyword).

 This line should be re-written:
   return h / numpy.sum(h,axis=0)
