What is the advantage in bandpass modulator than lowpass mod

[boki]

Hi, All:

What is the advantage in bandpass modulator than low-pass modulator?

Could you please explain more on 10.7MHz frequency point relationship?
How about the reciver or LNA ... something else, as long as the
advantage useful than low-pass.

Thanks a lot!

Boki.

I was thinking the same thing. I can see sort of what the answer

is, but the question is such a mess that I'm not sure it's worth even
trying.

I've never heard of a "bandpass modulator." The two terms seem
inconsistent at best. I wonder if he means 'bandpass filter?'

No idea what he's referring to with the "10.7MHz frequency point"
stuff, though I will say that 10.7 is used in an awful lot of IF strips.

Hi,

Actually I was surprised that anyone replied to this "boki". I've been
watching his posts for a while.His questions are so ill prepared, it is very
difficult to make sense of what he is asking. I tried to answer once, and
I've asked a few clarifying questions. He never got back, so I put him on
the "don't even bother " list. )

Cheers,
Cirip

Bandpass modulator makes signals are digitized in the IF band without
being down converted to the baseband.
