4 2 Dominance Fault Collapsing, DFC (*optional) 

Q2 27:54 For XOR gate There is no equivalent faults , EFC is cannot be done (10),(11), 0:00 0:00 (01)/(00) these three test vectors are essential test vectors of XOR gate So, DFC also cannot be done 27:54

Thank you sir for explaining the basics of DFT. I am not able to understand the XOR FFT asked at the last of the presentation, will anybody answer that for me?
