Cover Story
- Hot products 1999
Thousands of new electronic products come along every year. All, no doubt, are useful, and many are innovative, yet only a relative few generate real excitement. At EDN, we've noted that our readers respond in a really big way to about a hundred new products each year. Thus was born, in 1993, a year-end feature, the EDN Hot 100 Products. This year, we present our seventh annual installment. - From EDN Europe: 50 hot products 1999
Thousands of new electronic products come along every year. All, no doubt, are useful, and many are innovative, yet only a relative few generate real excitement. At EDN Europe, we've noted that our readers respond in a really big way to about 50 new products each year. Thus was born a year-end feature, the EDN Europe Hot 50 Products.
Design Features
- Category 6 cable—Gigabit Ethernet over copper
Gigabit Ethernet delivered over copper cabling challenges fibre and ATM for high-end enterprise LAN infrastructures. Lower installation costs together with reduced retraining and support issues persuade Gigabit Ethernet - Microfilter design promises peaceful coexistence between ADSL and the
voiceband
Even in a splitterless ADSL, filtering is still necessary to ensure high-frequency signal rejection and to perform an important impedance-blocking function.
