The phenomena of stochastic resonance of an over-damped second-order linear system with modulated dichotomous noise are investigated.

Stochastic resonance for dichotomous noise in a second derivative linear system;

Respond of petroleum log data to modulation noise;

Application of modulation noise to data acquisition of petroleum logging;

The technique of orthogonal narrowband noise modulation is based upon the classical formula of narrowband random signal.

While a noise modulation module used for canceling range ambiguity and mutual interference was proposed,modeled and analyzed.

Stochastic resonance (SR) is studied in linear systems under modulated noise when the modulated noise is a linear combination of multiplicative and additive noise.
