High speed (2 Mbit/s) data signaling project

last update on December 29, 2000

In a preceding article we evoked the construction of a broadband repeater, i.e. a polyvalent repeater able to transmit either fast scan amateur television signals, or high speed data flow. This article describes the specific section of the data transmission which is under development. The production and the use of the data, more complex subject, will be published later.

Why 2 Mbit/s ?

Overall synoptic

The pseudo random generator

The local data memory

The biphase coding

The Nyquist filter

The modem (reception part)

The regeneration

measurements: the eye pattern

The results

The schematic diagrams

The pictures

To be continued .......
