Signals & Systems - Trigonometric fourier series (even symmetry) - working examples

[@KUSHRAJ-db2fr]

thank you sir very simple explanation

[@Ram-sd6zh]

and do we need to find two equation even if we take 0 to pi value?

[@kandanoolradhika338]

Sir while calculating a_n we should consider formula as 4/T integral sir for even symmetry??

[@MrPprasanna]

Yes, you can use either formula 2/T or 4/T, with the help of symmetry we can minimise no.of calculations

[@MrPprasanna]

Symmetry is useful to minimize calculation part

[@kandanoolradhika338]

Sir for a_0 it is 2/T and for a_n it is 4/T for even symmetry

[@Ram-sd6zh]

what to do if the A is not given?

[@venkatesan9979]

Sir for this sum u r calculating slope but not for the last video sum that square wave one

[@harshrana3012]

because slope was 1

[@vanivatte9598]

Don't get direct answers sir explain each step plzz.....

[@suryapasupuleti8525]

Explain neatly not directly

[@shekhKAIF..]

Sir what is fourier series Coefficient of x(t)=t^2

[@kummarisudhamani3706]

Sir slope another one that is -A /pi

[@MrPprasanna]

Yes

[@lavakumar8554]

Thank you so much sir

[@Hoiu1106]

Thanks

[@jayanthtippa8852]

Sir why can't we take limits from 0 to 2pi

[@MrPprasanna]

We can also take 0 to 2pi, but length of the problem increases, instead of that if we take limits from -pi to pi then we can apply symmetric conditions

[@jayanthtippa8852]

@@MrPprasanna thank you sir,

[@jayanthtippa8852]

Pls share a link of 📝 notes

[@kkkk-mh8ym]

the a0 is value is A when we are taking the limit from 0 to 2pi

[@dhanashreeshukla255]

And how f(t+pi) ?

[@sushmarao8163]

Sir ,while calculating ao value why the limits has taken only 0 to π, what about -π to 0 ??

[@MrPprasanna]

You can also take limits from -pi to +pi

[@iqratariq8091]

Because f(t) is even ,u can replace -π to +π by 2 (0 to π)

Thank you very much sangeetha

Thankyou sir

[@MrPprasanna]

Thank you very much

[@dhanashreeshukla255]

How you find line equation by slop

[@MrPprasanna]

y-y1 = m (x - x1)

[@libu4624]

Book name please?
