例句與造句

1. Chirp spread spectrum is ideal for applications requiring low power usage and needing relatively low data rates ( 1 Mbit / s or less ).
2. Chirp spread spectrum may also be used in the future for military applications as it is very difficult to detect and intercept when operating at low power.
3. The Chirp Spread Spectrum PHY was added to the standard because CSS supports communications to devices moving at high speeds and at longer ranges than any of the other PHYs in the IEEE 802.15.4 standard.
4. Frequency-hopping spread spectrum ( FHSS ), direct-sequence spread spectrum ( DSSS ), time-hopping spread spectrum ( THSS ), chirp spread spectrum ( CSS ), and combinations of these techniques are forms of spread spectrum.
5. In August 2007, IEEE 802.15.4a was released expanding the four PHYs available in the earlier 2006 version to six, including one PHY using Direct Sequence ultra-wideband ( UWB ) and another using chirp spread spectrum ( CSS ).
6. It's difficult to find chirp spread spectrum in a sentence. 用chirp spread spectrum造句挺難的
7. While wideband FM uses more bandwidth, it can improve the signal-to-noise ratio significantly; for example, doubling the value of \ Delta { } f \,, while keeping f _ m constant, results in an eight-fold improvement in the signal-to-noise ratio . ( Compare this with Chirp spread spectrum, which uses extremely wide frequency deviations to achieve processing gains comparable to traditional, better-known spread-spectrum modes ).
