A voltage signal is connected to an oscilloscope and produces the following stable image. Voltage signal \( \downarrow \) The period of this signal is the time between \( \mathrm{A} \) and \( \mathrm{B} \). A and \( \mathrm{C} \). A and \( D \). A and \( \mathrm{E} \). A and \( F \). The signal is not periodic.
