In this lecture, I will introduce the mathematical model for discrete time signals as sequence of samples. You will also take a first look at a useful alternative representation of discrete signals known as the z -transform.

If you only want the integer positions, you can use np.arange instead of np.linspace and then create a scatter plot (plt.scatter(n, x)) or maybe a stemplot:

Plot contour (level) curves in 3D using the extend3d option. Project contour profiles onto a graph. Project contour profiles onto a graph

Aug 5, 2024 · A discrete time signal just means sampling your continuous signal at discrete time intervals. The simplest way this can be done is by increasing your step in n. n = [-5:0.25:5];

Oct 31, 2020 · Based on a lot of useful references especially (https://gist.github.com/neale/e32b1f16a43bfdc0608f45a504df5a84) here I share my code to plot the animated trajectory of a particle (in this case electron) using a 3D line/scatter chart.

Discrete-time signal: is a signal that is a function of the discrete-time variable t n; in other words, a discrete -time signal has defined values only at the discrete - time points t t n; so, a discrete time signal is a sequence of numbers indexed by integers. Example : x[n] o n..., 3 , 2 , 1 ,0 ,1 ,2 ,3 ,..., brackets indicates D-T signal ...

Jul 10, 2017 · I would like to plot a 3D trajectory, with time on the z-axis, longitude on the x-axis, and latitude on the y-axis, where all the objects' trajectories are on the same plot. How can I do this? This is my attempt but it does not work: from mpl_toolkits.mplot3d import Axes3D. import matplotlib.pyplot as plt. fig = plt.figure()

Launch an interactive application that can evolve the initial conditions u0s (vector of vectors) of the given dynamical system. All initial conditions are evolved in parallel and at exactly the same time. Two controls allow you to pause/resume the evolution and to adjust the speed.

Sep 8, 2017 · For discrete signals you can use the stem plot: n = [-12:1:12]; f =(n+5).*stepfun(n,-5)+2*n.*stepfun(n,0)+(n-10).*stepfun(n,10); stem(n,f,'marker','o','color','r') grid on; From the plot you can see that e.g. for n=10 the y-axis shows 35 which you will get by inserting n=10 into y[n]=3n+5 provided by Fat32 which confirms his results.

The Discrete-Time Scatter Plot Scope block displays scatter plots of a modulated signal, to reveal the modulation characteristics, such as pulse shaping or channel distortions of the signal. The Discrete-Time Scatter Plot Scope block has one input port.
