摘要:
The generation and some relevant properties of a class of periodic pseudorandom sequences called the maximum‐length sequence is described briefly. A simple and practical method is proposed to resolve a technical difficulty in using these sequences with FFT processing. The potential advantage of using a maximum‐length sequence as a test signal for architectural acoustic measurements is discussed and illustrated by an example.
