WebApr 22, 2024 · The first input to butter is already the filter order (so you have specified order 10 and tried to specify order 20 in the desginfilt function...). For the Butterworth-filter, MATLAB recommends to use the zero-pole-gain formulation rather than the standard a-b coefficients. Here is an example: WebDesign a 20th-order elliptic bandpass filter with a lower passband frequency of 500 Hz and a higher passband frequency of 560 Hz. Specify a passband ripple of 3 dB, a stopband attenuation of 40 dB, and a sample rate of …

WebNumerical 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.
