## Straight line fit using least squares estimate

by on July 15, 2007

Two points suffice for drawing a straight line. However we may be presented with a set of data points (more than two?) presumably forming a straight line. How can one use the available set of [...]

## Interpreting the output of fft() operation in Matlab

by on June 17, 2007

It might be interesting to interpret the output of the fft() function in Matlab. Consider the following simple examples. fsMHz = 20; % sampling frequency fcMHz = 1.5625; % signal frequency N = 128; % [...]
