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

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

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.

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.
