2004-05-10 Thread Ricardo Antunes
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
