Darboux transformation is applied to three classical potentials, namel
y the harmonic oscillator, effective Coulomb and Morse potentials to g
enerate exactly solvable potentials of elementary form. For every pote
ntial, the isospectral families of potentials are constructed. For alm
ost all potentials, a set of normalized discrete spectrum wave functio
ns is given.
