examples.oscilloscope.Lissajous Class Reference

Detailed Description

Uses the SineWave picker with the PrismPicker to generate Lissajous figures on an oscilloscope screen.

The wiring diagram of pickers in this program is given below:

We recall that a SineWave picker produces an output that corresponds to the equation A sin(ωt+φ), where A, ω and φ are pickers corresponding to amplitude, frequency and phase, respectively. The program depends on two parameters:

• the frequency ratio ω₂/ω₁ between the two sine wave pickers, noted m
• the phase difference ω₂(φ₂ − φ₁), where the term φ₂ − φ₁ is noted n

The program picks 1,000 points, and then plots them in a window that simulates the operation of an Oscilloscope. You can run the program by changing these values to produce various figures. Here are some classical examples:

Figure
Parameters	m = 1, n = 0	m = 2, n = 5π/8	m = 6/5, n = π/4

Caution: pay attention when entering ratios such as 4/3; you must make sure they are interpreted as a double; hence you must write 4d/3 (the d forces a cast to double).
