The formulae to describe ferroelectric effect in PbHPO4 (Lead Hydrogen Phosphate) type crystal are derived. For its simple modified model is used. Simple Green Function formalism is used for derivation numerically thermal variations of normal mode frequency (which brings ferroelectric effect) is obtained anomalous dielectric constant and spontaneous polarization are numerically calculated for PbHSO4 of example for different temperatures. Experimental data are matched with our values. Agreement is found good.
