Open the CIPO recordAbstract From the Canadian patent
An in-line distortion generator for coupling in-line with a non-linear device (NLD) produces an output signal of useful amplitude but with low composite , second order, composite triple beat and cross modulation distortions. The distortion generator comprises an instant controlled non-linear attenuator which utilizes the non-linear current flowing through a pair of diodes in , parallel with a resistor and an inductor to provide the proper amount of , signal attenuation over the entire frequency bandwidth. The distortion generator circuitry is always matched to the NLD thereby ensuring a frequency , response that is predictable and predefined. The distortion generator may also include a …

Why it's free to use
- Filed March 29, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 29, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 29, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
