      We present a detailed study of harmonic generation in Bi(Pb)SrCaCuO superconducting thick film prepared by screen printing technique. A comparative study of amplitude of harmonics of two films of different Jc have been carried out. The variation of amplitudes of the harmonics are studied as a function of magnitude of ac and dc field. The temperature dependence of amplitude of third harmonic (V3) is studied with increasing amplitude as well as frequency of ac field. These results are analyzed in the frame work of critical state model. V3-T curve also indicates the presence of two phases in Bi(Pb)SrCaCuO film.
