Cathodic Ray Tube simulator

We have developed a pc simulator of how would a cathodic ray tube would work in practice given specific values. The simulator includes 2 modes (sinusoidal and non-sinusoidal). The way the simulator works is by using the following formulas:

First formula:

Charge of the electron = $charge$

mass of the electron = $mass$

$$charge / mass$$

This formula will give us the element load ratio.

Second formula:

Voltage = $V$

Width of the plate = $W$

velocity of the laser = $v_x$

Distance between the plates = $d$

$$\theta_y = (VW/v_x^2 *d) (charge/mass)$$

$$\theta_x = (VW/v_x^2 *d) (charge/mass)$$

This formula will give us the $x$ and $y$ angle of the laser that would be the way that the laser would move on the screen.

To be able to draw the Lissajous shapes, we need to parameterize the formulas resulting in the following:

Third formula:

Frequency 1 = $f_1$

Frequency 2 = $f_2$

Phase = $\delta$

$$y = (W/v_x^2 * d )(charge/mass) (sen(f_1 * t))$$

$$x = (W/v_x^2 * d )(charge/mass) (sen((f_2 * t) + \delta))$$
