Well, please so me something other than your opinion to back that up,
because here's what I read:
"repeater -- a physical layer device that forwards bits, in contrast to
bridges and routers, which forward packets." Interconnections, Second
Edition Radia Perlman Page 530
"Repeaters fall into two categories: amplifiers and signal-regenerating
repeaters. Amplifiers simply amplify the entire incoming signal.
Unfortunately, they amplify both the signal and the noise.
Signal-regenerating repeaters create an exact duplicate of incoming data by
identifying it amidst the noise, reconstructing it, and retransmitting only
the desired information. This reduces the noise. The original signal is
duplicated, boosted to its original strength, and sent." MCSE: Networking
Essentials Study Guide Chellis, Perkins, Strebe Page 393-394.
"Repeater -- A physical layer device that only regenerates a bit stream. No
intelligence is associated with a repeater" ACRC Exam Cram Morgan, Shroyer
pg 410.
"repeater
Device that regenerates and propagates electrical signals between two
network segments. See also segment. "

Now I suppose we could argue that "bit" doesn't mean digital, but then we'd
have to argue exactly what is digital and is anything digital and then we'd
have to get into Manchester encoding etc, etc. However, if you plan to get
it right on any test you take, you ought to use these definitions, I did.

You are wrong there,
Think about this:
How can you regenerate a digital signal? By definition a digital signal is
made up of discrete values. If some of these are lost, which is why you
would want to regenerate the signal, how could you do this?
The last person was right with their definition, after all, if you are
talking about computers then you are talking about electron flows and these
are by nature analogue (ignoring quantum theory which is still a complete
mess. etc etc).
