摘要：
A high-pass Finite Impulse Response (FIR) filter has been successfully used by Ribeiro et al.(1997) to remove the low frequency components errors introduced in digital double integration, in order to reliably measure displacements using accelerometers. However, the FIR filter can introduce a time aliasing error at the beginning and at the ending of the signal. The purpose of this paper is to discuss this phenomenon.
