{[sin(omega(t-tau))]/pi(tau-KTs)}delta(tau-KTs) dtau

apologies for the terrible way I have written this out, but I don't know how to use symbols or if you can on this

also don't know if this helps but

omega is wavelength, K is a constant from part of a sum and takes values from - infinity to +infinity

Ts is a constant

and the integral came from trying to convolve the bit in the curly brackets with the delta func.

I tried converting sine into exponential form but so far no luck.

If anyone can decipher what I've written above and can help I'd appreciate it,

thanks
