本文提出了一种使用并联梳状滤波器的简单基音检测方法。我们可以通过检测十二个并联梳状滤波器中较小的输出来了解音乐声音的音高。每个梳状滤波器具有与每个音调及其谐波频率相对应的零点，因此与输入音调频率相对应的梳状滤波器的输出具有较小的频率分量，并且表现出比其他梳状滤波器的输出更小的输出。我们可以以 98.2%（双音）和 91.1%（三音）的概率检测到音高。
This paper proposes a simple pitch detection method using the parallel connected comb filters. We can know the pitches of a musical sound by detecting the smaller outputs in twelve comb filters connected in parallel. Each comb filter has zero points corresponding to each pitch and its harmonic frequencies, and so the outputs of the comb filters corresponding to input pitch frequencies have smaller frequency components, and show smaller outputs than other comb filter ones. We could detect the pitches with a probability of 98.2% for double tones and 91.1% for triple tones.
