Fourier transform of a tetration function

[tommy1729]

Hi,
(snip)
2) Since a pulse is usually depicted as Heaviside function, or delta function, with infinite growth speed of front, and, since it is known that no discontinuity can propagate faster than light, for modeling of real life pulses moving via systems could we use tetration approximations to the front? Such front can have any speed > c ( since it will represent phase or group speed) and, for a given (even linear) system, one could perhaps create a tetration ( or higher) front that propagates with any given speed?

forgive me for saying this , but the above is nonsense.

what does lightspeed has to do with tetration or fourier transform ?

that is a rhetoric question , dont answer it.
