Filter Coefficients

Hello,
Thanks for a wonderful forum.
1. I have a simple FIR filter doing the following. Output is the sum of
previous hundred samples. After 100 samples everything is reset, and the
summation ...
CIC Filter Length

I am reading about CIC filters used for an Sigma Delta converter. In that
the author mentions that
- For a 2nd order filter, decimating by N, the length of the impulse
response is 2N+1
- For a ...CIC Filter Length

I have an input signal that is generated using the following statements.
Fs = 1.4287e6 (Sampling Frequency)
Fbin = 32 (FFT Bin Number)
N = 2^17 (FFT points)
t = 0:N-1
input = A*Sin(2*pi*(Fbin/N...Matlab 'mfilt.cicdecim' and 'filter' functions
analog_fever - 2010-07-12 15:47:00
I am trying to see the response of a CIC filter for a set of input data.
I created the filter using the function
Hd = mfilt.cicdecim(100, 1, 3)
set(Hd, ...

I am designing filter to do decimation at the output of a Sigma Delta
modulator. Here is the spec -
Sampling frequency - Fs - 1.4MHz
Decimation factor - D - 100
Input - 3 bits
Output resolution...Frequency response from Z transform
analog_fever - 2010-06-28 14:06:00
I am trying to plot the frequency response of a system given its transfer
function. I know about the freqz function in Matlab. The problem is that my
Z transfer function has fractional order term in i...CIC filter response
analog_fever - 2010-06-18 13:47:00
I designed a CIC filter and am trying to plot its response.
fclk (sampling frequency) = 1.4MHz
D (Decimation factor) = 100
Order = 3
Input bits = 3
