Carrier signal generation is performed by a 6AH6 tube with an additional 6AH6 buffer stage followed by a 6AG7 output amplifier.
42.
When that occurs, the system transmitter turns on, encoding the CTCSS tone on its carrier signal ( the output frequency ).
43.
All radios in the system start decoding after they sense a carrier signal then recognize the tone on the carrier as valid.
44.
A greater source of error is atmospheric conditions, which can degrade the microwave carrier signals that GPS satellites transmit and introduce errors.
45.
Carrier signals of Quad LPs popular in the 1970s were at 30 kHz to be out of the range of human hearing.
46.
The station broadcasts were fully automated after this, and there were some periods during which a carrier signal was broadcast without any programming.
47.
The snag is that multi-carrier signals do not travel as far as single-carrier ones, so they require the construction of expensive repeater stations.
48.
The name " suppressed carrier " comes about because the carrier signal component is suppressed it does not appear in the output signal.
49.
Every hovercraft is equipped with a transceiver, used primarily to broadcast a pirate carrier signal into the wireless network that forms the Matrix.
50.
The changes in the carrier signal are chosen from a finite number of M alternative symbols ( the " modulation alphabet " ).
