Abstract :
This paper presents a digital acquisition method for low frequency signals immersed in high frequency noise. The method reduces the aliasing with no use of hardware aliasing filters. Several one-dimensional chaotic maps with different Invariant Probability Density Function (IPDF) are used to generate the sampling times. Comparisons with previous results using random sampling are made for several Finite Impulse Response (FIR) filters.
