- MP3解码原理:首选将MP3数据帧解包,解出帧头信息和边带信息;然后采用霍夫曼解码解出比特分配信息;接着在逆变换中利用频谱系数,在综合滤波器中将32位子带合并成一个宽带信号。18个频谱值执行32位IMDCT(逆改进型离散余弦变换),将生成的576个频谱值变换成长度为32的18个连续的频谱。通过18次运算,多相位综合滤波器将这些频谱转换到时域,完成波形重构,生成立体声PCM音频数据。-jiema and bianma

- 电路中使用了锁相环音频译码器LM567。LM567是一种模拟与数字电路组合器件,其电路内部有一个矩形波发生器,矩形波的频率由5、6脚外接的R、C值决定。输入信号从3脚进入LM567后,与内部矩形波进行比较,若信号相位一致,则8脚输出低电平,否则输出高电平。8脚是集电极开路输出,使用时必须外接上拉电阻。 将LM567第5脚上幅值约为4V的标准矩形波,通过R1引至三极管VT1的基极,使接在VT1发射极的红外线发射管导通并向周围空间发出调制红外光。-PLL circuit used in the
