We study a model in which the electroweak symmetry is dynamically broken by technicolor interactions and the symmetry-breaking is communicated to the quarks and leptons by a weak doublet of scalar fields. The scalars may be regarded as elementary or as light bound states arising from strong extended technicolor interactions. This model is unusual in that it can provide a heavy top quark without generating large flavor-changing neutral currents. Our work focuses on the model's phenomenology, particularly the oblique electroweak radiative corrections. We demonstrate that while oblique corrections and FCNC effects limit the allowed parameter space, the model remains viable. In particular, if the scalar is relatively heavy, the model can accommodate a wide range of top quark masses.
