Open the CIPO recordAbstract From the Canadian patent
A system and method (Figs. 1-2) for dynamically optimizing occupied bandwidth of a direct modulated FM radio is disclosed in which a remote receiver , periodically monitors the received output of a local transmitter and compares the received output occupied bandwidth to a reference level. If the monitored level of the demodulated signal unacceptably exceeds the reference level an error mesage is developed and sent back to the local transmitter to cause the output of the local transmitter to be adjusted to more closely conform to the desired spectrum output mask. An alternative embodiment (Fig. 4) is also disclosed in which temperature and operating frequency are monitored at the …

Why it's free to use
- Filed July 17, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 17, 2018.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
