Is there a Matlab function like 'freqrespest' to get the filtering-based frequency response estimate of a fixed-point multi-rate filter? For example, a digital halfband decimation filter.
Or is there any existing Matlab code that I can simply copy and use ?
Thanks a lot!

fvtool?
Frequency Response Estimation不支持多速率滤波器啊
就拿半带来说吧,你只把他当一个FIR filter就好了,后面的降两倍频和有限字长等没有
关系吧,其他多数率的就要看具体情况了。
貌似有个工具包用来设计数字滤波器的吧
可以直接对比量化前后的频率响应
多速率滤波器是指?抽取?
唔,那个只能看到系数量化的影响
我想通过实际的滤波看到字长截断的影响
