A method and a system for determining the amplitude and/or the phase of the output signal of a transmission link dependent upon the amplitude of the input signal (AM-AM and/or AM-PM characteristic) impresses a test signal (s(t)) on the transmission link (14), measures the response signal (e(t)) resulting from the test signal (s(t)) by amplitude and/or phase distortion in the transmission link (14) and determines the amplitude response ( e(t) ) of the response signal (e(t)) and/or the phase responses (.phi.s(t) (.phi.E(t)) of , the test signal (s(t)) and of the response signal (e(t)) dependent upon the amplitude response ( s(t) ) of the test signal (s(t)). The amplitude response ( …

Listed from its CIPO record in Patent Yard's archive of Canadian patents past their term. Its claims, description and drawings are in the CIPO record and on Google Patents, and the Claude kit works from them.
Why it's free to use
- Filed April 12, 2006 and granted May 19, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 12, 2026.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
