IIR数字滤波器实现
IIR数字滤波器实现:直接每隔一个取一个采样值,这样就可以得到8k采样率的数据。但是这样明显会有问题。按照采样率变换理论,首先应该通过一个低通滤波器,滤掉[pi/2, pi]这个区间上的频率,以防止下采样造成的频率混叠。这个低通滤波器在很多书上都用FIR滤波去实现,并且可以用FIR滤波的多相结构去实现。这样滤波和下采样过程可以互换位置。即先下采样再进行多相FIR滤波。

Optimized-JS-V8
面向对象、设计模式与性能
有些C/C++开发者有些奇怪的观念。他们认为使用面向对象和设计模式会降低程序的性能。但V8证明了这种观念是错误的。V8的实现使用了许多设计模式,但依然非常高效。
下面列出V8中使用的两个模式:
工厂模式
当Javascript引擎执行一个脚本时,引擎为遇到的每个变量、函数或数组都创建一个实例。JSObject是所有这些对象的父对象(Object oriented, design patterns and performance
Some C/C++ developers have some strange ideas. They believe that the use of object-oriented and design patterns will reduce the performance of the program. But V8 proved that this idea is wrong. V8 implementation uses a number of design patterns, but still very efficient.
The following lists the two models used in V8:
Factory mode
When a Javascript engine s a script, the engine creates an instance of each variable, function, or array encountered by the engine. JSObject is the parent of all of these objects.)
