can you explain at which frequency you got this well sampled signal, and what is your source may be it si also sampled as the same frequency that is why you get the same result.
thanks that is really what i search for but the question is how to select the frequency I mean the equations .. which used to know which frequency is selected and deal as short circuit ??
Really thanks for help,
but I mean is this cables are restrictly frequency dependence, I mean if I have 2 modulated signals (frequency modulation) Low and high frequency the LF with low power and the HF with high power I can reject the high power with rejecting this frequency part.
the diods is...
1)First I want to know about how can one make frequency dependent quarter cables (coxial)(lamdah\4)?
2) Then what is the relation of these cable length with the input power?
3) then I would be able to protect my reciever from reflection high pulse using these cables.
Hii Iam new in this field, Please I want to build 1/4 wave cables and cross diodes together to stop high power at 90 MHz frequency for exaample, I want help how can I build some thing like this and what is the equations to choose the right length depending on the frequency...
