15. This result is equivalent to stating that the response of the bridge to a step input in voltage is the same as the response of the bridge to an impulse in velocity, a result already demonstrated by Freymuth (Ref. 2) which led to the development of the original square wave test.

21. Even with a hypothetical bridge of infinitely flat frequency response, there is always a limit in the usable frequency range since the electronic noise rises with the square of the frequency.
