I am performing a FFT on my accelerometer data, but I am having issues with the 2nd-order Butterworth filter and pca interpretation. Please find a snippet of my code below. RE…
Can System Objects be used with webcam video acquisition for live video in Video and Image Processing Blockset 3.0 (R2010a)? I would like to have a live video that is captured by…
Why do I receive two different responses when I try to discretize the same analog filter using the ELLIP and ELLIPAP functions in Signal Processing Toolbox 6.12 (R2009b)? I am…
I am running the fftdemo.m file that ships with MATLAB. The resulting power spectral density plot shows two peaks with different amplitudes. Because the original two sine waves t…
Hi Everyone, I faced a problem to apply Wavelet for denoising ECG Signal I know there are three steps you have to do which are : Transform the noisy ECG signal to wavelet domain …
Hi, i am trying to generate a periodic decaying exponential signal in the time interval between -5 and 100 . I am trying to visualize it like a sawtooth waveform (but reversed and …
I am converting an audio signal to freq domain and back to time domain at different fft sizes to see the trade-off between time and freq resolution. I thought that if I take t…
I'm about to design a couple of IIR filters in FDA tool. The cutoff-frequency normally is -3 dB, but for Chebyshev and Elliptic it seems like it's only -1 dB. Am I doing somethi…
Has the algorithm for fdesign changed in Signal Processing Toolbox 6.13 (R2010a) as compared to the previous versions? I am using fdesign.decimator to design an equiripple filter…
Hello Experts, The output of the FIR filters is convolution of the input signal and the filter kernel. In that case, the length of the output signal should be greater than input si…
