Okay, so i'm going to classify whether these four random processes are either discrete time or continuous time, as well as being discrete space or continuous space.
00:16
So for the purposes of this exercise, i'm going to just write d or c for discrete or continuous in each of these four processes.
00:24
So the first one, we're looking at the board rate of a modem, which is recorded every 60 seconds.
00:33
So what we are really doing in this process here is we are recording the outputs every 60 seconds.
00:45
So there's a sort of accountable way of measuring the board rate at each time.
00:53
So because of that, this will be a discrete time process.
00:58
And the board rate itself is just some, let's say, probably real number, so to speak, you know, between zero and infinity possibly, some positive real number.
01:14
So it'll be a continuous space.
01:17
So when you think about doing the last three, think of discrete versus continuous time being sort of the thing of it as whether the time variable is discrete or continuous and discrete versus continuous space you can think of this as the whether the x so the random process itself is a discrete or continuous variable so let's just sort of breeze through the last very quickly the number of people logged into facebook throughout the day.
02:00
So the number of people is sort of the variable we're looking at...
