Re: matlab - output branch
You can use the "Shift" key and then grasp the output line of the block,and then you can get the copy output line of the block.
fixing setup and hold violations
timing violation seems that somthing happens in the clock tree or your code.
Maybe you can find the problem in your synthesis process.
zero means the ascending of the spectrum from the zero to inifinty.
So if you add a zeros at zeros ,that means you want to emphasis the part of the high frequancy band part of the signal.
you can look for the itu-G series speech codec for that.
such as g721,g723.1,g729..etc.
and amr.
maybe that will help you.
there are many free source code in the internet.
Re: what is CIC filter?
Cic filter is a simply filter for sampling conversion.
It just only use add and substraction for the filter,and there is no need to use multiplication and division for that.
But if you use cic filter,the spectral domain will be needed a compensation filter for compensate...
