modulated time signal造句
例句與造句
- In 1977, the current phase modulated time signal was added to the transmissions.
- The drawback of using phase-modulated time signals lies in the complex instrument grade receiving hardware required for using this time signal reception method.
- In addition to the amplitude-modulated time signal transmission this information is also transmitted since June 1983 by DCF77 via a phase modulation of the carrier wave with a pseudorandom noise sequence of 512 bits length.
- Corrected instrument grade DCF77 receivers using the amplitude-modulated time signals with accompanying antennas oriented tangential to the transmitter's antenna in Mainflingern to ensure the best possible interference-free time signal reception at fixed locations can achieve a practical accuracy uncertainty better than ?2 milliseconds.
- Normal low cost consumer grade DCF77 receivers solely rely on the amplitude-modulated time signals and use narrow band receivers ( with 10 Hz bandwidth ) with small ferrite loopstick antennas and circuits with non optimal digital signal processing delay and can therefore only be expected to determine the beginning of a second with a practical accuracy uncertainty of ?0.1 second.
- It's difficult to find modulated time signal in a sentence. 用modulated time signal造句挺難的
