Low Pass Butterworth Filter 1.0 Description |
|---|
Description: In this code I have implemented a low pass filter using the filtfilt command. It plots the actual data, filtered data and the filter characteristics. Its pretty well commented out. Feel free to change portions of the code depending on your requirements i.e. the data, cutoff frequency, order of the filter etc. License: Shareware Related: portions, Change, commented, depending, Requirements, Order, Frequency, cutoff, pretty, characteristics O/S:BSD, Linux, Solaris, Mac OS X File Size: 10.0 KB Downloads: 461

Simple Zero Phase Distortion Multiplier-less Gaussian Low-Pass & High-Pass Digital Filter of a Linear Chirp.
Low-pass filters allow the low frequency components of an input signal to pass through while attenuating (reducing) high frequency components. Measurement noise fall into the high frequency range of the signal spectrum, while the underlying...
In this study, windowing-based Finite Impulse Response (FIR) filter design method is implemented for four regular filters ( Low Pass, Band Pass, Band Stop and High Pass). Detailed steps are described. The related codes are uploaded to the website...

The calculation of filter parameters with BUTTER is expensive. Therefore ButterParam stores calculated parameters in a lookup-table to accelerate repeated calls with the...
Important Note:
This model could only be compatible with MATLAB 7(R14) and CCS 2.21. It might work for other versions of MATLAB & CCS but for that Sampling Rates & data types of various simulink blocks might have to be adjusted...
The INTERPFT function does sinc interpolation by taking an FFT, padding its end with zeros, and then taking an IFFT. Essentially, INTERPFT resamples the signal after low-pass filtering it.
Instead of putting all zero padding at the FFT...
