Abstract
The effect of thermal noise is studied on the statistical behaviour of the superposition of squeezed and displaced number states. In our analysis we h ave employed the s-parametrized characteristic function. For such superposi tion states exact expressions for quasiprobability distribution functions, normalized second-order correlation function, photon-number distribution an d phase space distribution are obtained and discussed in detail.
