摘要
本文讨论了离散哈特莱变换,并给出了快速哈特莱变换基2算法的推导以及实际的计算量,据此提出了一种实用的实时音频频谱显示结构。
From the definition of DHT radix - 2 FHT algorithm is inferred and the corresponding amount of calculation is discussed. Based on this algorithm, we flexibly introduce a practical structure to present realtime FFT spectrum of sound signal input at low cost.
