Mel-频率

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

数制和编码

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
