Abstract

Изобретение относитс  к телевизионной технике и может быть использовано в телевизионных приемниках дл  автоматической настройки на сигналы работающих (елевизионных станций. Цель изобретени  - повышение точности настройки. Устройство содержит блок автоподсгройки частоты гетеродина 1, компараторы 2 и 3, триггеры 4 и 5, ключи 6-8, генератор пилы 9, селектор каналов 10 и резистор 11, Устройство обладает повышенной точностью настройки, и возможностью установки уровн  по принимаемому сигналу, т.е. избирательностью по уровню. 3 ил.The invention relates to television technology and can be used in television receivers for automatic tuning to the signals of operating (television stations. The purpose of the invention is to improve tuning accuracy. The device comprises a self-tuning unit for local oscillator 1, comparators 2 and 3, triggers 4 and 5, keys 6- 8, a saw generator 9, a channel selector 10 and a resistor 11, the device has improved tuning accuracy, and the ability to set the level according to the received signal, ie, selectivity by level.
