  We present the convolution integral for fermion pair production in the
electroweak standard theory to order O(alpha) including also soft photon
exponentiation. The result is complete in the sense that it includes initial
and final state radiation and their interference. From the basic result -
analytic formulae for the differential cross section - we also derive the
corresponding expressions for total cross section and integrated
forward-backward asymmetry. The numerical importance of different contributions
for the analysis of experiments at LEP/SLC energies is discussed.
