Signal Operations: Scaling and Addition

[@lmd168]

Great video, thanks, if only my university lecturers are half as good as you. I don't even know why I pay my tuition fees when I find materials which are 100 times better on youtube.

Scale (multiply) by -1, then add.

[@milosmijatovic86]

identical subject with material and courses with signals ans systems on my faculty... now i am gonna pass it :)

[@norfweezi]

thanks, but what about subtraction?

[@srinivasanpt626]

question: let x(t) be a signal with x(t)=0 for t

[@aris9106]

Now I have the same question

[@bishwajitbordoloi6276]

What happens when x(2t--1)

[@olgael7680]

i think you will draw that x(2t) graph then shift it 1 unit on the right side !! check out graph shifting on google , hope it helps !
