What is a Chebyshev RF Filter - the Basics » Electronics Notes

Numerical Instability of Transfer Function Syntax. In general, use the [z,p,k] syntax to design IIR filters. To analyze or implement your filter, you can then use the [z,p,k] output with zp2sos.If you design the filter using the [b,a] syntax, you might encounter numerical problems. These problems are due to round-off errors and can occur for n as low as 4.
