radiotelegraph channel造句

例句与造句

1. A radiotelegraph channel comprises two stations and a radio wave propagation path between the two stations.
2. To protect receiver circuitry, radiotelegraph channels on nearby frequencies and antennas must operate in so-called " half-duplex " mode wherein the stations at either end alternate between transmitting and receiving ( because e . g . simultaneous transmit and receive is simply not possible ).
3. The mid-symbol listening and interruption capability provided by the short but ubiquitous Morse code silent periods during QSK or full break-in operation on " half-duplex " radiotelegraph channels creates the " illusion of apparent continuous two-way contact " allowing radiotelegraph operators to feel as if they are sharing a " full duplex " channel.
4. On half-duplex channels the radio station : receiver, transmitter, and antenna or antennas are usually interconnected by so-called " "'transmit / receive " or ( T / R ) switches "'that effectively "'connect and disconnect the receiver and transmitter from the antenna "'or antennas as required by the radiotelegraph channel protocol in use.
5. The aforementioned considerations : ( i ) prevention of receiver desensitization during transmit periods, ( ii ) prevention of damage or destruction of receiver AFE input circuitry during transmit periods, ( iii ) enabling transmitting stations to listen between signals and, ( iv ) providing efficient, fluid and fluent two way communications on half-duplex radiotelegraph channels, are the four prime motivations and considerations driving the development of radiotelegraph channel " full break-in QSK technologies ".
6. It's difficult to find radiotelegraph channel in a sentence. 用radiotelegraph channel造句挺难的
