This WebApp aims to illustrate how discrete oscillations works.
Use the slider to select a frequency that will correspond to an angle illustrated in the first plot. As you slide, the angle increases / decreases and the plot to the right updates in real time with a discrete sinusoid corresponding to that selected frequency. The first plot also shows the multiple of the angles that will form the sinusoidal signal.
