Summary
In the present paper we study the coherent and the squeezed states in phase space. From the wave functions of the coherent and the squeezed states we calculate their corresponding Wigner distribution functions. Especially the calculation of the corresponding Wigner functions for the above states permits the determination of the mean values of position and momentum and thus the Heisenberg uncertainty relation. In fact, from the related results, we conclude that the uncertainty relation of the coherent and associated squeezed states is the same.
