1. DCS command signals are transmitted at 10.7 MHz using spread spectrum technology. 2. Widespread digital spread spectrum technology and encryption has made eavesdropping increasingly difficult. 3. Spread spectrum puts a single transmission over a wide range of frequencies.4. Worse still, we're adopting complex multiplexed digital signalling and employing'spread spectrum 'techniques. 5. Frequency hopping is a basic modulation technique used in spread spectrum signal transmission. 6. In 1995, digital spread spectrum ( DSS ) was introduced for cordless phones. 7. Spread spectrum systems rely on excess signal to noise ratios for sharing of spectrum.8. Some wireless intercom designs reduce this interference by using " digital spread spectrum ". 9. The PN encoding is a form of spread spectrum modulation. 10. The new 2 . 4-gigahertz phones are all spread spectrum .
