In summary, the problem is to plot the continuous-time signal x(t)= 10e^-3tu() over the range -1≤t≤5 by breaking up the time range into two ranges t1=[-1 0] and t2=[0:.1:5] and then concatenating the results. The provided code suggests using a programming language, but there are issues with plotting the function. More information is needed to assist with this problem.

Problem:
x(t)= 10e^-3tu()
Plot the continuous-time signal over the range -1≤t≤5
Break up the time range into two ranges t1=[-1 0] and t2=[0:.1:5]. Then concatenate the results, i.e. t=[t1 t2].

My answer was:
t= 0:.3:-1;
x= exp(-3*t).*u(t)
plot (t,x)
axis (-1 0 -3)

Can't plot the function because of issues.
Please help.

Welcome to the PF.

There are some typos in your post that make it hard to follow. Also, you do not specify what programming language you are supposed to plot the function with, and why you are not able to plot it.

Please fix the typos and explain to us why you want us to try to plot your homework for you.
 

FAQ: Solving Time-discrete Systems Problem: Plotting x(t)= 10e^-3tu()

What is the equation for x(t)?

The equation for x(t) is x(t)= 10e^-3tu().

What does the variable t represent in the equation?

The variable t represents time in seconds.

How do you plot x(t) on a graph?

To plot x(t) on a graph, you need to first choose a range of values for t. Then, plug in each value of t into the equation to calculate the corresponding value of x(t). Finally, plot these points on a graph with t on the horizontal axis and x(t) on the vertical axis.

What is the significance of the term e^-3tu() in the equation?

The term e^-3tu() represents the rate at which x(t) changes over time. It is also known as the decay factor and determines the shape of the graph for x(t).

How can this equation be used in real-world applications?

This equation can be used in a variety of real-world applications, such as modeling the decay of radioactive substances, analyzing population growth or decline, and predicting the behavior of electrical circuits.
