If you disassemble a _cheap_ repeater (Like the kind used as cable
extenders, You'll find mosfet's configured as amplifiers. The analog signal
varies depending on the physical Layer you are using. I.e. a rs-232
interface swings between -15V and +15V.

Repeaters are digital devices that regenerate the DIGITAL signal for
retransmission. AMPLIFIERS amplify analog signals.

Repeaters and Hubs are Physical Layer Devices. Repeaters amplify analog
signals to reduce attenuation. Hubs provide multiple connection points for
a single network segment. Hubs are sometimes called multi-port repeaters.
Switches and Bridges are Layer 2 devices. They look at the Layer 2 address
(MAC address), and make decisions about the destination of a packet based on
the information contained therein.

What si wrong with "layer 2 devices" - that is what they are??
