RE: IIRIIR Filter Functions not working in higher oder and lower frequency specification

[ChandJB]

Dear Team,

Using matlab command, "[b,a] = cheby2(7, 50, 1/50, 'high') " , filter spec : order-7, freq spec normalized to 0.01 and magnitude specification: 50 dB. I have generated the co-efficient, and passed to IIRIIR Filter Functions and observed irrelevant output, but same has been done for order-6, freq spec normalized to 0.01 and magnitude specification: 50 dB co-efficient generated and passed to IIRIIR Filter Functions, observed the expected output. Requesting to give the analysis.

Thanks in advance.

Hi ChandJB.

To resolve this issue could you please provide any reproducer with expected and irrelevant output?

This is the example  of correct using ippsIIRIIR_32f

Thanks.

Andrey.
