An AGC circuit of a high definition signal receiver includes a non-coherent AGC signal generator for generating a first AGC signal according to the magnitude of said IF signal a coherent AGC signal generator for generating a second AGC signal according to the magnitude of the segment synchronizing signal, and a selector for selecting the second AGC signal when the segment synchronizing signal is detected and the first AGC signal when the segment synchronizing signal is not detected and providing them to a tuner/IF demodulator. The amplitude of the received signal is controlled within a short period of time using the non-coherent AGC method having a fast response time before a system is …

Why it's free to use
- Filed June 9, 1997 and granted May 2, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 9, 2017.

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