Testing Digital Recorders

Part of the Modern Acoustics and Signal Processing book series (MASP)


The proposal put forward in this book involves the acquisition of calibrated signals by means of a digital recorder to be later analyzed using computer software to get sophisticated mesaurements such as band spectrum or exceedance levels. However, the accuracy of the results is limited by the performance of the recorder. In this chapter we study the tests to be performed on the recorder to ensure it is suitable for its use as part of a measurment system, including the verification of its frequency response, effect of temperature, self-generated noise, linearity, transient response and uncertainty. Example results for a consumer digital recorder are also provided.
