We show how Pauli–Villars regularization works in the construction of renormalized Hamiltonian for two examplars of quantum systems with singular pertuabations. The systems are the scalar 3-dimensional particle interacting with $\delta$-potential and the infrared extensions of the quadratic forms of the gaussian functional of the ground state in the quantum field theory.
