Abstract Lissajous figures are measured on glow and pseudoglow discharges under 11.85 kHz voltages in helium at atmospheric pressure. Based on mathematical analysis of the measured Lissajous figures, physical processes of discharges are investigated. The results show that a Lissajous figure is divided into some lines and some curves, which are of alternating appearance in a figure. The line represents a process of the applied voltage charging the capacitance formed by the gas in the discharge gap and the barrier dielectrics, and the curve a process of the gas in the gap discharge. The number of the discharges in one half of the applied voltage is dependent on the amplitude of the applied voltage. With the order of the lines appearance in a figure increases, the slope coefficient of the line enlarges. And with the amplitude of the applied voltage grows, the discharge inception voltage reduces, and even changes into a negative value from a positive one.
