Web15 mei 2013 · imfilter () does a similar (though not exact) thing. The more pointed the filter is in the middle, the less filtering it will do, and the bigger the window size, the more blurring it will do. For example, a Gaussian filter does less blurring (filtering) than a box filter of the same window size. Web3 feb. 2015 · A lot of people confuse natural frequency with cut off frequency. The natural frequency is the frequency the system wants to oscillate at. The cut off frequency (or -3dB freq) is just when the transfer function has a magnitude of 0.707.
