Description

тора 10 частотно-модулированного сигнала на его выходе по вл етс  рабочий импульс при смене частот. Рабочий импульс с выхода частотного дискриминатора поступает на второй вход схемы совпадени  9, котора  срабатывает только тогда, когда на ее входах одновременно присутствуют сигналы с выходов обоих каналов. Импульс с выхода схемы совпадени  9 поступает в блок логики устройства телеконтрол  и одновременно поступает на вход формировател  И импульса сброса, который при срабатывании устанавливает частотный дискриминатор 10 в исходное состо ние.A torus 10 of a frequency-modulated signal at its output appears a working pulse when changing frequencies. The working pulse from the frequency discriminator output goes to the second input of the coincidence circuit 9, which only works when the inputs from the outputs of both channels are simultaneously present at its inputs. The impulse from the output of the coincidence circuit 9 enters the logic unit of the telecontrol device and simultaneously enters the input of the shaper AND reset pulse, which, when triggered, sets the frequency discriminator 10 to the initial state.
