[@bhawna15diaries]

please add some more problems on signal construction to clear the concept....this was awesome...but still needs to watch some more to get into d concept...plz

[@ladybuggaming25]

x(t) =(3t+1) (u(t +2)+u(t-2)) can you in this question?

[@farazmathsfh9205]

How to construct this signal sir x(t)=tu(t)-2(t-2)u(t-2)+2(t-4)u(t-4) i have confusion in it.

[@omardelacruz9442]

Say we have a positive ramp function with slope = 1 starting at t=0, then at t=1 the signal falls and commences as a horizontal line from t=1 to t=2. How would you write this when there's two things that happen at t=1?( adding a positive slope to make it horizontal then subtracting a step function??)

[@AdamPanagos]

Yes, what you said sounds perfectly right. If "two things" happen at the same time, just put two signals at that time. You could put a unit step to shift things, and a ramp to change the slope. Hope that helps, Adam

[@zRo_Radius]

Sir, how you consider 1 at u(2) , because according to your previous video it should be 2 yup.

[@AdamPanagos]

No, I'm pretty sure the videos are correct. Can you tell me what time in the video you think there's an error? u(t) is the unit step function and is equal to 1 for all t >=0 and zero otherwise So, u(2) = 1. r(t) is the unit ramp function and is equal to r(t) =tu(t). So, r(t) is equal to t for all t>=0 and zero otherwise. So r(2) = 2*u(2) = 2*1 = 2. Did you maybe mix up the r(t) and u(t)?

Very useful!

[@pappagnes9754]

what is u(-t) if u(t)=1 for t>=0?

[@AdamPanagos]

It's just the time-reversed version of u(t). The signal u(-t) is equal to 1 for all t

[@devanshverma9823]

Thank you it really helped !!💯🙏

[@AdamPanagos]

Glad I could help, thanks for watching. Adam

[@mubashirahmad6643]

how can we get -1 slope

[@Dasn0thing]

Don't you have to create a ramp function that cancels the first where the value is held from -1?

[@AdamPanagos]

That's what the final ramp term r(t-2) does. If the last term was not present, we would continue to decrease with a slope of -1 for all time. Adding in r(t-2) adds a slope of +1 at time t = 2 to cancel it out. So, the final slope at t = 2 is -1+1 = 0. Thus, we hold a constant value for the rest of time. This constant value happens to be zero. Hope that helps.

[@aakarshankhanal8227]

Didn’t understand the checking part. How is u(5) =1?

[@AdamPanagos]

u(t) is the unit step function. It's "on" for all t >=0 and "off" for all t < 0. When the unit step is "on", it has a value of 1. So, u(5) = 1 since the argument of the unit step function 5 > 0 and thus it's on. Hope that helps, Adam

[@hananalbaloushie3005]

you said that the ramp function is equal to 0 if t is less than or equal to 0! Is that true? I checked it online and my professor told us that the ramp function is equal to 0 only if t is less than 0. if ramp of 0 is t then the x(t) won't be equal to 1 at t-1.

[@AdamPanagos]

Either definition is the same. You can define it as: r(t) = t for t>=0 and 0 for t < 0 Or you can define it as: r(t) = t for t>0 and 0 for t

[@ladybuggaming25]

x(t) =(3t+1) (u(t +2)+u(t-2)) how to solve this question? What to do with 3t+1 part?

[@AdamPanagos]

I'm not sure exactly what you're asking. Are you trying to plot this signal?

[@ladybuggaming25]

[@essayehfares8235]

confused how the last one is r(t-2) isn't that 0*r(t-2)

[@AdamPanagos]

During times 1 < t < 2, the signal is decreasing with a slope of -1. Once the ramp function at time t= 2 turns on with slope, the overall signal now has slope 0. Hope that helps, Adam

thank you so much sir ..but i have badly in need the matlab code of this singal.. please sent the code as soon as possible..

[@AdamPanagos]

I'm sorry, but this video example doesn't have anything to do with Matlab so there's not any Matlab code to go along with it.
