Digital Signal Processing

Lab work 1

Create all primitive signal and sound them using Visual Studio and C#

1. Sine
2. Triangle
3. Square
4. Sawtooth
5. Implusle with different duty cycle

Lab work 2

Determine the period of the signal by taking count of points and calculate signal haracteristics.

Lab work 3

Decompose the signal into Fourier series. Show the Amplitude and Phase spectrums of the signal. Create Low Frequency and High Frequency Filters.

Create a smoothing to the signal to remove the noises and other not necessary elements from it.
Methods:

1. Average arithmetic window.
2. Parabola in 4 degree.
3. Median Filtering window.

Image Filtering

1. Filtering the image with 2D Median filtering windows to remove noises and other not necessary elements from it.
2. Bluring a picture using Gauss filter.
3. Show a countour of the picture using Sobel filter.
