How to plot only 4U?

[@Topperly]

Hi Nazia, I'm sorry, but I didn't get your question completely. Could you please elaborate? If you are referring on how to plot 4u(n), all you have to do is scale every sample in u(n) by 4. :)

[@nazianhossain8110]

X(n) = Ur(n) - Ur(n-3) + 4U How to plot that 4U? Thank u so much for replying.

Could you please provide the timestamp of the moment you are referring to so that I can take a better look?

[@nazianhossain8110]

Sorry, not given, told to sketch the equation with only this

[@Topperly]

Okay. In that case, could you please help me understand what is 'U' referring to - Is it a constant or unit step signal? And I'm assuming r(n) is ramp signal.
