Is it possible to obtain the transfer function of a signal that has a variable delay?
For instance, I have a signal consisting of 10 samples: 0,1,1,1,1,0,0,0,0,1
If I would apply a unit delay to the signal, the transfer function would be z^-1 and the signal is now:
What would be the effect e.g. transfer function if I delay the rising edge of the pulse by 1 delay as above, but the falling edge would be delayed by 2 samples? The signal then would be:
Could this be derrived as a combination of z^(-1) and z^(-2) or this transfer function is non-linear?
Thank you for your answers.
