Alternatively, the duration of the first period may be 1ms, or 2ms, or 3ms, or 4ms, or other time length, which is not limited by the present application.
Alternatively, the duration of the second period may be 1ms, or 2ms, or 3ms, or 4ms, or other time length, which is not limited by the present application.
