Abstract :
A simple analysis leading to expressions for the multiplier output spectrum and the effective probing signal of an impulse response measurement system using sliding correlation is presented. Evaluation of the expressions shows the presence of self-noise at the correlator output and its dependence on the system parameters. The dynamic range of the measurement can be studied using the expressions derived. The incorporation of different correlation filter characteristics in the expressions for the effective probing signal is easily achieved
