### How to find lattice coefficients when k2=1?

$H(z)=1+2z^{-1}+z^{-2}$ We know the formula $a_{m-1}\;(k)=\frac{a_m\;(k)-k_m\;a_m\;(m-k)}{1-k_m\;^2}$ Here $k_2=1$ That makes $a_{m-1}\;(k)=infinity$ How to find lattice coefficients of all pole IIR ...

### Lattice structure-Lattice coefficients-Sign positive or negative?

This is the question $$H(z) = \frac{1}{2 + 1.4z^{-1} + 1.8z^{-2}}$$ My professor has told that we don't need to take those 2 values as negative and instead we can take them as positives(with the ...

### How to find Lattice structure when k3=1?

I could not type this so I got a snip shot. Pardon me for that. Here k3=-1. That means the formula Here we will get x/0=∞. How to solve this question?

### CIC filter internal register truncation

I try to implement CIC filter with truncation in hardware, but there is some misunderstanding. For some reason the output signal is broken. My filter is N = 6, R = 20, M = 1, Bin = 16, Bout = 16. (...

### Why should wavelet re-synthesis produce an output when the main component is suppressed and what does this mean for denoising?

I understand that aliasing occurs in DWPT if the wavelet used is of low order since the "filters" are not perfect and the combination of down sampling and overlapping between bands causes ...
