the stationary signal f(t)=cos(2*pi*5*t)+ cos(2*pi*10*t)+ cos(2*pi*20*t)+ cos(2*pi*50*t)having frequencies of 5,10, 20and 50 Hz at any given time instant.MATLAB program can be implemented to plot the stationary signal mentioned above:Clear... Platforms: Matlab

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself.... Platforms: Matlab

The purpose of this tutorial is to illustrate the usage of Kalman Filter by a simple example.The problem: Predict the position and velocity of a moving train 2 seconds ahead, having noisy measurements of its positions along the previous 10 seconds (10 samples a second).Ground truth: The train is...
