The spectral representations of the fixed-energy amplitude of the symmetric and the general Poeschl--Teller potentials are summed via a Sommerfeld--Watson transformation which leads to a simple closed-form expression. The result is used to write down a similar expression for the symmetric and general Rosen--Morse potentials, exploiting the close correspondence that exists between the two systems within the Schroedinger theory and the path integral formalism via a Duru--Kleinert transformation. From the singularities of the latter amplitude the bound and continuum states of the general Rosen--Morse potential are extracted.
