MATLAB: Downsampling Seismic Signal from 200sps to 100sps signal processing Hello How could I downsample my seismic signal from 200sps to 100sps (from 0.005 sample rate to 0.01 sample rate)?? Thankss Best Answer resample(xx,1,2)if your data is vector or if array with channels stored as columns . If you have a timeseries then a different resample applies with different parameters . Consider also converting to a timetable object and using retime() Related SolutionsMATLAB: RMS of sampled signal ac_signal = YourSignal - mean(YourSignal(:));rms = sqrt( mean(ac_signal.^2) ); MATLAB: Downsampling image Hi, You can use dyaddown() from the Wavelet Toolbox. x = randn(8,8); % this gives you 1st row, 1st column, 3rd row, 3rd colum, etc y = dyaddown(x,'m',1); % now this gives you 2nd row, 2nd column, etc y = dyaddown(x,'m',0);Or you can use downsample() from the Signal Processing Toolbox. This gives you one polyphase matrix. Y = downsample(x,2,0); Y = (downsample(Y',2,0))';This gives you the other: Y1 = downsample(x,2,1); Y1 = (downsample(Y1',2,1))';Hope that helps,Wayne Related Question200 X 200 MatrixI need to under sample, perfect sample, and over sample a sinusoidal signal.Downsampling of RPM tracesSampling Audio at 11025 sample/sec in MATLABMatlab coding for downsampling……..……
