TELEVISION SIGNAL SELECTION DEVICE |
摘要 |
<p>A television signal selection device comprising the fact that a band to-be-searched within a channel is checked successively from the upper side toward the lower side thereof with a video signal detection output and an AFT voltage output, by the use of a unit search frequency band which is prescribed by the characteristic of a lower-side adjacent voice trap on the lower frequency side and the PLL lock-in range of a video signal demodulator on the higher frequency side. In addition, the checked results are stored as the positions of the unit search frequency bands of the band to-be-searched.</p> |
