cbadc.analog_system

Analog systems

This module provides a general cbadc.analog_system.AnalogSystem class with the necessary functionality to do transient simulations, compute transfer functions, and exposing the relevant system parameters as attributes. Additionally, several derived convenience classes are defined to quickly initialize analog systems of particular structures.

Functions

chain(analog_systems)	Construct an analog system by chaining several analog systems.
sos2abcd(sos)	Transform a series of biquad (second order systems (sos)) filters into their A,B,C,D state space model equivalent.
stack(analog_systems)	Construct an analog system by stacking several analog systems in parallel.
tf2abcd(b, a)	Transform a transferfunctions into a controllable canonical state space form.
zpk2abcd(z, p, k)	Convert zeros and poles into A, B, C, D matrix

Classes

ButterWorth(N, Wn)	A Butterworth filter analog system
Cauer(N, Wn, rp, rs)	A Cauer (elliptic) filter's analog system
ChainOfIntegrators(beta, rho, kappa)	Represents an chain-of-integrators analog system.
ChebyshevI(N, Wn, rp)	A Chebyshev type I filter's analog system
