Sources for 1D Signal Decimation - Books & URLs

[makris]

Can anybody tell a few good sources for 1dimentional signal decimation? Either books or URLs?

I know how to use the "decimate" function in MATLAB thus perform decimation, but my goal is to code a function in MATLAB (or C) to perform the same process. That is why I need the theory behind decimation.

Thanks

i don't know your application but in decimation filtering and down sampling is perform in a paralle way . suppose if we down sample first and then we will filter with low pass filter we have to face alising while if we do filtering first then down sample then also it its useless as we have to spend a lots of memory to store the FIR data so what we do is every time when we delay signal by one sample,we down sample it and multiply it with FIR coeeficient in this way we acchieve both the things

y(n)=[N-1]\sum[i=1]h(i)*X(Mn-i);

i know its a bit confussing but try to google

for your question. There are many good sources available for learning about 1D signal decimation. Here are a few recommended books and URLs:

1. "Digital Signal Processing: Principles, Algorithms, and Applications" by John G. Proakis and Dimitris G. Manolakis. This book provides a comprehensive overview of digital signal processing, including a chapter specifically on sampling and reconstruction, which covers decimation.

2. "Understanding Digital Signal Processing" by Richard G. Lyons. This book covers the fundamentals of digital signal processing, including a chapter on sampling and reconstruction that discusses decimation.

3. "The Scientist and Engineer's Guide to Digital Signal Processing" by Steven W. Smith. This online resource provides a thorough introduction to digital signal processing, including a section on sampling and reconstruction that covers decimation.

4. "Signal Processing for Communications" by Paolo Prandoni and Martin Vetterli. This book covers signal processing techniques specifically for communications applications, including a chapter on sampling and reconstruction that discusses decimation.

I hope these resources will help you gain a better understanding of the theory behind decimation and assist you in coding your own function in MATLAB or C. Best of luck with your project!
