I'm having a lot of trouble with one of the questions in the first part of the signals and systems unit when trying to find systems. The problem states that the input to a system is 0 for 0 less then n and 1 for 0 greater than or equal to n. It also states that the output is 0 when n is less than zero and is equal to the sequence 10, 1, 1, 1, 1, . . . when n is greater than or equal to zero. Can anyone help me understand how to go about finding the difference equation for this problem?
