differentiation property

hi can anybody clarify me that is there any limitaion on using the differentiation property of the CT-FT ?

thnx

purna!
 

Please Explain your question clearly
 

Hi Purna,

in my opinion, the limitation (or better referred to as condition that has to be fulfilled) for the differentation (derivative) property of the CTFT is that the CTFT has to be differentiable. This is like when you do derivative on functions in time domain, i.e. the function shall be differentiable in time domain, which usually needs the function only has anomaly (outlier, not well behaved) at only several places. For example unit pulse is no well behaved at the jumps, but it still could be differentiate.

It may help you.

best
