It is useful at least in data analy-sis (interpolation is a form of regression), industrial design, signal processing (digital-to-analog conversion) and in numerical analysis. It is one of those The interpolation factor is simply the ratio of the output rate to the input rate. It is usually symbolized by “L”, so output rate / input rate=L. Tip: You can remember that “L” is the symbol for interpolation factor by thinking of “interpo-L-ation”. 3.1.4 Is there a restriction on interpolation factors I can use? Yes.

Matlab has a lot of functions for interpolate, depending on what you're trying to do. You don't need a toolbox for it, either. This works as per the program written. As the code is burned into it, the user can not see the code. Now, within your program you can have a conditional statement which serves as...

Interpolation - easy code with Matlab. Matrixlab-examples.com Fortunately, Matlab has also several built-in function to interpolate values with different methods (' interp1 ', ' interp2 ', ' interp3 ', and ' interpn '). ' interp1 ' is called one dimensional interpolation because vector y depends on a single variable vector x.

Let M/L denote the decimation factor, where: M, L ∈ ℤ; M > L. Increase (resample) the sequence by a factor of L. This is called Upsampling, or interpolation. Decimate by a factor of M; Step 1 requires a lowpass filter after increasing (expanding) the data rate, and step 2 requires a lowpass filter before decimation. Therefore, both ...

MATLAB is an interactive software package which was developed to perform numerical calculations on vectors and matrices. Initially, it was simply a MATrix LABoratory. However, today it is much more powerful: • It can do quite sophisticated graphics in two and three dimensions. •
SRC designs use the basic properties of decimation and interpolation to change sampling rates. Decimation is the reduction of the sampling rate and interpolation is the increasing of the sample rate. 1.1.1 Decimation A reduction of sample rate (decimation) by a factor of M is achieved by sequentially discarding M-1 samples and
Luckily they have thought of that and the excellent decimate function in matlab will antialias your data and then downsample it. DECIMATE Resample data at a lower rate after lowpass filtering. Y = DECIMATE(X,R) resamples the sequence in vector X at 1/R times the original sample rate. The resulting resampled vector Y is R times

The quoted paper doesn't explain the bit growth exactly, neither for decimation nor interpolation filters. Besides the Matlab tool, I would always refer to the original Hogenauer paper introducing CIC filters. Bit growth in the comb section of interploation filters is in fact simple, one bit per stage. --- Quote End --- Thanks FvM.

For example, the following Matlab code upsamples the FIR 2 coefficients by 2, from f s /2 to f s: b2_up= zeros(1,21); b2_up(1:2:21)= b2; Figure 3 shows the coefficients b2 and b2_up. The code has inserted samples of value zero halfway between each of the original samples of b2 to create b2_up. b2_up now has a sample rate of f s. But although we ...
