1. A system for testing a signal path to produce a complex frequency response of the signal path, said system comprising:

  • a transmitter connected to a first location of the signal path, said transmitter for transmitting a predefined test signal, having a short duration, along the signal path;

    a receiver connected to a second location of the signal path wherein the receiver receives the test signal as an impaired test signal;

    a digital signal acquisition unit comprising a digital signal processor connected to the receiver, wherein the digital signal acquisition unit acquires the impaired test signal and processes the impaired test signal with an unimpaired test signal previously stored within the digital signal processor to produce the complex frequency response of the signal path between the first location and the second location.
