Figure 3. Simulation model

On the next stage in is necessary to adjust above given blocks. Their properties are necessary to be set as follows:

Sine Wave Source Block:

• Sample Model set to Discrete;

• Output complexity set to Real;

Complex to Magnitude-Angle Block: define output to Magnitude;

Vector Scope block: find Axis properties toolbar and set frequency rage to [-Fs/2…Fs/2] and Frequency Unit: Hertz;

Simulate a sine curve with amplitude 1 and frequency of 1KHz. Sampling time set to 8KHz. The output signal select to be a real. Set the size buffer to 16. Choose Window Function to be Blackman. Obtain the spectrum for different types of frequency range. Explain the obtained results.

Report

1 Submit your Matlab code.

2 Submit your calculation and hand sketch of the signal.

3 Submit the plot of magnitude (power), Amplitude and Phase of the signal.
