TLV320AIC3204: First-Order IIR Filter Coefficients for ADC

Sadanori Kato

Part Number: TLV320AIC3204

Hi,

Are the coefficients(N0, N1 and D1) obtained by using the following calculation tool "Coefficient Calculator For Digital Biquad Filters" able to be applied to TLV320AIC3204 if applying the high pass filter to the first-order IIR filter for ADC with the PRB_R1 processing block ?

Hi, Kato-san,

Your comments are correct, the coefficient calculation tool can be used to generate the coefficients for different types of filters, including First Order filters like the IIR on PRB_R1. On the tool coefficients window, you can see a "1O" note, which means the coefficients generated correspond to a first-order filter.
