yeah i understand that now by proving that the output is only delta[n] when connecting an IIR filter with H(z)=1/(1+0.25z^-Ne), so ty!
If i wanted to find the impulse response for the filter, what should i do??
If Ne = 1 it would be easy... just use the table; (-0.25)^n * u[n]... if Ne was 2...
Calculated the inverse transfer function filter
Another question arose tho... why is this not a FIR filter???
You said it was an IIR filter, but i cant seem to understand how this is using feedback??
hey!
I'm having some problems removing a pulse from my signal.
I have the output y[n]=x[n]+0.25x[n-Ne], where Ne = 2205.
System function H(z)=(z^Ne + 0.25)/z^Ne
What i want to do is to remove the pulse 0.25*delta[n-Ne].
Im very new to DSP, so what i first did was to try cascading FIR...
