On Delta Modulation

Bell System Technical Journal, 1972
We show how the steady-state distribution and the mean squared error of a delta modulator with an ideal integrator can be computed exactly when the input signal to the modulator is a stationary Gaussian process with a rational power spectral density.

Schrödinger equation with \(\delta'\) and \(\delta"\) potentials.

1994
Summary: We analyze the positive and negative energy solutions of the Schrödinger equation, with derivatives of \(\delta\) functions as potentials. It is found that these potentials act as localized, infinite barriers and the wave functions outside the barrier may be obtained by requiring that they vanish at the barrier.
