Which command is used to plot discrete signals?

It is common to graph a discrete-time signal as dots in a Cartesian coordinate system. This can be done in the Matlab environment by using the stem command. We will also use the subplot command to put multiple plots on a single figure.

What is continuous-time and discrete-time signal?

Discrete-time signals are defined at the discrete moment of time and the mathematical function takes the discrete set of values. Continuous-time signals are characterised by independent variables that are continuous and define a continuous set of values.

How do you generate a sinusoidal signal in Scilab?

Sine Generation in Scilab

1. Sine is simply a function that operates on an argument.
2. The sine function does not generate unique values for every argument.
3. Thus, one cycle of sine values corresponds to a 2π range of argument values.

Can a discrete time signal look like a sine?

A discrete-time sinusoid can have frequency up to just shy of half the sample frequency. But if you try to plot the sinusoid, the result is not always recognizable. For example, if you plot a 9 Hz sinusoid sampled at 100 Hz, you get the result shown in the top of Figure 1, which looks like a sine.

Which is an even signal in a discrete time system?

Even signal component: x e(n) =1 2 [x(n) + x( n)] Odd signal component: x o(n) =1 2 [x(n) x( n)] Note: x(n) = x e(n) + x o(n) Dr. Deepa Kundur (University of Toronto)Discrete-Time Signals and Systems5 / 36 Chapter 2: Discrete-Time Signals and Systems

How are the sample times of an interpolated signal plotted?

The interpolated signal shows the original sample times by plotting every 8 th sample as an orange dot. The interpolated version includes an initial transient response of length equal to that of the interpolation filter (121 samples).
