Frequency Bias and Jointly Owned Units (JOU) correct answer: BAs that use dynamic schedule or pseudo-ties for a jointly owned unit share responsibility for it in their bias settings. Fixed schedules for JOU require host BA to include total response for them in their bias setting. Frequency Bias and BA frequency response correct answer: BAs must maintain a frequency bias that is equal to or greater than the BA frequency response. If the frequency bias is less than the frequency response, A...
