Does anyone can point out problems or disadvantages of
using the frequency response of transducers and/or
amplifiers (e.g. due to GBP limitations) to avoid
aliasing?
If for instance I use a transducer with a response
that drops past 100 kHz and an amplifier with a
similar frequency response, and
Yes, it makes sense. Though, you must be sure nothing enters into your
electroacoustic chain. Other than real sounds, you also have also to
consider any electric interference coming from the environment in
which you're working.
Just as an example, while working on an oceanographic ship I
