I just want to thank neso academy for helping engineers to this extent....your videos have proved beneficial not only for students but also for many teachers as well. I therefore want to send my warm regards for reaching and helping engineers in building their base

@manshimuskan1636 6 лет назад

A lot of love and respect to you and the whole team of neso Academy for the great job you are doing guys keep supporting engineers like this this will give our country well qualified engineers

@kiyoboss2424 Год назад

* -4r(t-2) because at pont 2 singal is downword turn and down turn consider to be - ve and slope is 4 = 4-0/(3-2) , and the pont of turning is 2 so we take r(t-2) and not r(t-3)

@duchoang3635 2 года назад

@sarthak gupta at t = 3 the slope tends to upward when compared with 4r(t-2), so should we add the 4r(t-3) signal?

4:11 is it correct to say : +ve sign when turning anticlockwise, -ve sign when turning clockwise for all 360 degrees?

@ojastewari5933 2 года назад

the change in slope would be zero so it wouldn't matter.

@ABHISHEKKUMAR-ym5fq 6 лет назад

while going from 5 to -2 U just substract 5-(-2) means initial -final but in other cases U just substract final - initial

@sibaprasad1803 6 лет назад

already the sign is taken negative as the signal is undergoing downward shift . if you want to follow the "final-initial" then do not take the negative sign beforehand. so either way you will get the negative sign. so do whatever you are comfortable at. good luck.

@magjoy_6 3 года назад

@@PoluBalaji If you see the diagram clearly, at t=3 the diagram is not going down to the 4th quadrant but -4r(t-2) is representing the diagram towards down(4th quad). So, we have to change the slope to 0 at t=3 by adding +4r(t-3). Actually '+4' is the slope value. If you don't add this 4r(t-3) term at t=3 the diagram would be different.

the correct answer is x(t) = 2r(t+2) - 2r(t) - 4r(t-3) you can plot it on Matlab and check it is right. here's the code: t0=-2:0.01:0; x0=2*(t0+2); t1=0:0.01:2; x1=4*ones(size(t1)); t2=2:0.01:3; x2=-4*(t2-3); t=[t0 t1 t2]; X=[x0 x1 x2]; plot(t,X,'linewidth',2) xlabel('time') ylabel('amplitude') grid on
