Matlab Bode and Nyquist plots
Matlab includes classical control theory analysis functions such as for Bode plots. Bode plots are useful for determining the behavior of linear time-invariant systems in filters and controls. Again, we are working with Matlab’s tf objects. Let’s define a third-order … Continue reading
More Matlab filtering
Previously, I covered discrete-time filters. Matlab has functions for continuous-time filters as well. The transform of interest is the Laplace transform. As before, we obtain a transfer function, this time in the s-domain. We have the numerator B(s) and denominator … Continue reading
Fun with filters
In this post, I am going to review a number of Matlab functions useful for discrete-time signal processing. The transfer function Suppose we have a discrete-time signal x[n] sampled with frequency Fs, and wish to pass it through a filter … Continue reading
Monday DSP drive-by
I have found a couple of neat links for learning digital signal processing (DSP), from a practical angle. Steve Smith has a free online DSP book. If you’re into Matlab, or even you’re just using Matlab to get into DSP, … Continue reading
