Abstract: In digital signal processing systems, the multiplication products cause parasitic noise which affect the system properties. Creating low sensitivity in the digital signal processing system cause the systems to reduce the noise and ultimately improve the performance of the system. In this paper, we have used the low sensitivity recursive first order digital systems to study the multiplication of products at poles. Thus, this work can enable the best performed fields of the studied digital signal processing systems.

Keywords: Quantisation Effects, Round-off Errors, First-order LP and HP DSP Networks, All-pass First-order Digital Systems Study of Parasitic Noise in Digital Signal Processing Systems
