carrier transmission मीनिंग इन हिंदी

उदाहरण वाक्य

1. They supplied short-haul 24 channel PCM carrier transmission equipment to NTT in 1965.
2. While these suppressed carrier transmissions are efficient in terms of transmitter power, they require more sophisticated receivers employing envelope detection.
3. A related concept is the combination of a single carrier transmission with the single-carrier frequency-domain-equalization ( SC-FDE ) scheme.
4. However it is possible to talk about a modulation index exceeding 100 %, without introducing distortion, in the case of double-sideband reduced-carrier transmission.
5. An additional function provided by the carrier in standard AM, but which is lost in either single or double-sideband suppressed-carrier transmission, is that it provides an amplitude reference.
6. This doesn't work however for single-sideband suppressed-carrier transmission ( SSB-SC ), leading to the characteristic " Donald Duck " sound from such receivers when slightly detuned.
7. The single carrier transmission, unlike SC-FDMA and OFDM, employs no IDFT or DFT at the transmitter, but introduces the cyclic prefix to transform the linear channel convolution into a circular one.
8. This prevents carrier signals from being dissipated in the substation or in a tap line or branch of the main transmission path and grounds in the case of anything happening outside of the carrier transmission path.
9. The modulation system used ( single-sideband suppressed-carrier transmission ) and the ITU standard remained the primary method of telephone service distribution until it began to be supplanted by digital techniques from the 1980s onwards.
10. On the other hand, with suppressed-carrier transmissions there is " no " transmitted power during pauses in the modulation, so the AGC must respond to peaks of the transmitted power during peaks in the modulation.
