You can also specify signal factor levels using a range and increments. You can specify a range by typing two numbers separated by a colon. For example, 1:5 displays the numbers 1, 2, 3, 4, and 5. You can specify an increment by typing a slash "/" and a number. For example, 1:5/2 displays every other number in a range: 1, 3, and 5. |
