Define the variables given below and plot the graph using the stem (plot2D3) command. Get the amplitude, sine wave frequency and the sampling frequency of the graph. Amplitude Sine wave frequency : Sampling frequency : Draw the graph and give some analysis Use Scilab to run the program and show the code that is being used

Sol6:

The given program is:

T=0:0.2:20; A=5*sin(T);

In this program, T is a vector that starts at 0 and goes up to 20 in increments of 0.2. This vector represents the time axis of the graph.

A is another vector that is calculated using the sine function, where the amplitude is 5 and the frequency is not explicitly defined, but is determined by the time axis vector T.

To plot the graph using the stem command in Scilab, we can use the following code:

T=0:0.2:20; A=5*sin(T); plot2d3(T,A)

The amplitude of the graph is 5.

The sine wave frequency is not explicitly defined in the program, but can be determined by calculating the period of the wave. Since the sine function has a period of 2p, the period of this wave would be 2p divided by the frequency. From the graph, we can see that the period is approximately 6.2 units of time. Therefore, the frequency of the wave would be 2p divided by 6.2, which is approximately 1.01 Hz.

The sampling frequency of the graph is 5 Hz, which is the reciprocal of the time increment in the T vector (0.2).

The graph shows a sine wave with an amplitude of 5 and a frequency of approximately 1.01 Hz. The waveform appears to be periodic and continuous, indicating that it is a continuous-time signal.
