This application note considers the design of frequency- selective filters, which modify the frequency content and phase of input signals according to some specification. Two classes of frequency-selective digital filters are considered: infinite impulse response (IIR) and finite impulse response (FIR) filters. The design process consists of determining the coefficients of the IIR or FIR filters, which results in the desired magnitude and phase response being closely approximated.

This sample program generates two sine waves called X and Y. It will then calculate the normalized magnitude and phase of the two waveforms using the following formulas: Mag = sqrt(X^2 + Y^2)/sqrt(GainX^2 + GainY^2) Phase = (long) (atan2PU(X,Y) * 360) The program will prompt the user to change the gain and frequency of the X and Y waveforms.

Abstract-In this paper, simple autonomous chaotic circuits coupled by resistors are investigated. By carrying out computer calculations and circuit experiments, irregular self-switching phenomenon of three spatial patterns characterized by the phase states of quasi-synchronization of chaos can be observed from only four simple chaotic circuits. This is the same phenomenon as chaotic wandering of spatial patterns observed very often from systems with a large number of degrees of freedom. Namely, one of spatial-temporal chaos observed from systems of large size can be also generated in the proposed system consisting of only four chaotic circuits. A six subcircuits case and a coupled chaotic circuits networks are also studied, and such systems are confirmed to produce more complicated spatio-temporal phenomena.
