摘要：Mel-频率是模拟人耳对不同频率语音的感知。（人类对不同频率语音有不同的感知能力，对1kHz以下，与频率成线性关系，对1kHz以上，与频率成对数关系） 在Mel频域内，人对音调的感知能力为线性关系，如果两段语音的Mel频率差两倍，则人在感知上也差两倍。转换公式：B(f)=1125ln(1+f/700) 其中f为频率，B为Mel－频率 阅读全文

摘要：1 数制 数制是多位数码中每一位的构成方法及从低位到高位的进制规则，包括十进制、二进制、十六进制和八进制等。2 码制 不同的数码不仅可以表示数量的大小，而且还能用来表示不同的事物。在后一种情况下，这些数码已经没有表示数量大小的含义，只是表示不同事物的代号而已。这些数码成为代码。实际中，编制代码时需要遵循一定的规则，这些规则就叫码制。摘自：数字电子技术基础（第五版）习题全解P3 唐亚楠 主编 阅读全文
