This paper presents a new algorithm for universal tone detection, which uses two outputs of the Goertzel filter as inputs to a neural network. This algorithm is referred to as the neural tone detector (NTD). Detailed analysis and comparison with exis

This paper presents a new universal tone detection algorithm using the quotient of two Goertzel filter outputs. This algorithm will be referred to as the Goertzel quotient algorithm (GQA). A detailed analysis and comparison with existing solutions in

Summary form only given. In this paper, an exact sampled-data representation of continuous-time systems are presented. Based on the well known discretization technique for linear systems, we derive new results for nonlinear systems, especially for Vo

This paper proposes a polyphase representation for Volterra filters. To derive the new realizations the well known linear polyphase theory is extended to the nonlinear case starting with Volterra filters. Both the upsampling and downsampling case are

This work addresses the problem of approximating the sampled input-output (i/o) behavior of continuous-time nonlinear systems using discrete-time Volterra models. For an exactly band-limited nonlinear system for which a Volterra representation exists
