Signum Function

[@manishaprajapati689]

sgn(pie-3) = sgn(3.14-3) = sgn(0.14) = 1 ans.

Well said 👍👍👍👍👍👌

[@malkavian6275]

just wanna let you know you carried me through my digital electronics course, ty!

[@aserez3020]

You draw brackets perfectly.

[@benguyldrm4819]

you explain everything way better than my professor, so thank you very much!

[@ayebillaavoka4242]

pi is positive. sgn(pi - 3) shows that the original function, sgn(pi) is shifted to the right by three steps. Therefore, sgn(pi - 3) is 1

[@Happymind1331]

Yeah ....can we say its delayed signal ?.….. I thought 3.14-3 =positive nonzero so it would be 1 😅

Thanks a lot sir!!! I am so grateful to Saraswati Mata that we, students, are blessed with such amazing teachers like you, and the answer to your HW quest is positive 1, I was able to solve questions like these now Thanks to my parents, Saraswati Mata and teachers like you sir, Thank you very much Jai Shri Ram

[@pummysingh8523]

Sir, in the last property.. how can differentiation of any constant term be equal to 1 or -1? Then for all t !=0 value of signum function will get equal to 0..!!

[@Vishwa2757]

u should not put the value of t and then take differentiation. First take diff of |t| . U will get negative slope (slope = -1) for t < 0 and positive slope (slope =1 ) for t>0.

[@ruchimadaan573]

Sir some books represent signum fn like u(t)-u(-t).How this thing can be derived.Pls elaborate ths issue also.

[@RAJESH-yl8lw]

u(t)+(-u(-t)) and analyse waveform

[@ruchimadaan573]

RAJESH BAIRWA how this thing can be derived?

[@RAJESH-yl8lw]

Ruchi Madaan first draw the wave form of u(t) and -u(-t ) then join both fn together.and compare with sgn fn

[@bhabanishankardas9800]

Sir, can you please elaborate the 4th property. It's a little bit confusing.

[@adarsh4physics]

Thank u very much sir The ans is 1

[@BrightAcdemy1]

Thanks ❤❤❤❤❤sir

[@prajitvishnukarthik8886]

Will it shift to right side for sign(t-t0)

[@rekhamishra982]

sgn(pi-3) = 1 since, pi = 3.14 (approx.) therefore, pi - 3 = 3.14 - 3 = 0.14 as 0.14 > 0 that implies, sgn(0.14) = 1

[@neerajcheryala9602]

If sgn(t) is discontinuous at t=0, then how is it equal to zero at t=0??

[@neerajcheryala9602]

Thank you, so you are telling that discontinuity is nothing but the function taking value that it's not supposed to take at that point according to the regular signal interpretation. In this example, sgn(t) is -1 for all t

[@sagarkafle9259]

unit step signal also discontinuous at t=0 but could be differentiated how come, signum function not be differentiated if discontinuous

[@KAME_JEE]

1 because the value of π is 3.14 - 3 = 0.14 > 0 = 1

[@devprakash7468]

How we can represent Sigman function as exponentially

[@amanahmad4809]

Yeah that's also my ques

[@rohan30497]

Can you explain about the last property? You told previously that sgn(t)= mod(t)/t so d/dt(modt/t) should be equal to 2del(t).

[@carzycults6119]

I think that ,from the previous equation |t| = sgn(t)*(t) by differentiating this , we can get " d/dt |t| = sgn(t) "by considering sgn(t) constant ie., either 0 or 1 it might be the way how they get

sgn(180-3)=1

[@apostolosmavropoulos177]

π=3,14 rad , or π=180 degrees but u must be carefull , -3 is a number (like rad) and not an angle(degree) so there are no degrees in the brackets in this example..the right answer is : sgn(π-3) = sgn(3,14-3) = sgn(0,14)=1. if u want it in degrees u must convert 3 rad to degrees like this 3*180/π =171,88 degrees. now it is ok to write sgn(π-3)=sgn(180-171,88)=1 cause everything is in degrees.i hope i helped
