I am looking to evaluate the following definite integral involving Dirichlet kernel and sinc function with phase.
beginequationI(d) = int_-infty^infty fracsin[N(k^"-k^')]sin(k^"-k^') fracsin(c(k^"-k^'))c(k^"-k^') fracsin(Nk^')sin(k^') fracsin(ck^')ck^' exp(ik^'d+iphi(k^')) rect Big(frack^'k_0Big) dk^' endequation
Seems to be difficult due to Dirichlet kernel. Thank you in advance.

No, the Dirichlet kernel cancel and with $int_-infty^infty$ instead of $int_0^k_0$ it would have a closed form.

Kindly explain how they cancel? btw, I corrected for missing constant in the sinc argument.

With your $c$ they don't anymore. Why would you want to evaluate $int_0^k_0$ ? With $int_-infty^infty$ it still has a closed form

$int_0^k_0$ ? --> I have optical low pass filter that limits spatial frequencies.
