DIGITAL, PSEUDOCONTINUOUS SOUND DETECTOR ARRANGEMENT. |
| abstract |
Method and apparatus (Fig. 1) for sampling input signals (20) of different frequencies and providing a detect signal when the input frequency has a predetermined value suitable for use as a tone decoder for continuous tone controlled squelch systems. The method utilizes digital pseudo continuous correlation tone detection, and includes sample matrix limiting (26 and 28) to provide rapid reverse burst turnoff, as well as background detection to avoid adjacent channel reverse burst turnoff falsing. |
