Open the CIPO recordAbstract From the Canadian patent
The invention relates to a device (FPGA) which using digital means which can , be advantageously created in an ASIC or FPGA allows for the generation of a , digital signal (dms) with predeterminable phase angle for the rapid synchronization of two modulated carrier signals (bs ts). By using digital , means or logic elements (PSP1 2, SSP1...4, MUX, ST) the typical disadvantages of analog circuits, such as temperature or voltage drift are avoided. In , addition, the economic and technical resources required for creating the device (FPGA) provided for in the invention are minimized.

Why it's free to use
- Filed July 13, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 13, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 13, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
