'iir' — The function designs a minimum-order infinite impulse response (IIR) filter and uses the filtfilt function to perform zero-phase filtering and compensate for the filter delay. The 4th order IIR fi lter implemented is a Lo w Pass Filter with the specifications shown in Table 1. TABLE 1: FILTER CONSTANTS The Low Pass Filter is designed using a digital filter design pac kage (DFDP™ b y Atlanta Signal Processors Inc.). The filter package produces filter constants of the structure shown in Table 1. Table 2 shows We will build the topology of the single-pole IIR digital filter from the single-pole passive RC filter shown in Figure 1. In Figure 1, the low-pass filter output is available across the capacitor and the high-pass filter output is available across the resistor. For example, low-pass filters preserve low frequencies and reject high frequencies.

Hi, The following code reacts to low frequencies. I am trying to understand the code: // Arduino Beat Detector By Damian Peckett 2015 // License: Public Domain. IIR Filter Specifications: Butterworth filter The example of IIR Butterworth Low-Pass Filter at sampling frequency of 1 kHz and cut-off frequency of 300 Hz and filter order of 5 using Impulse Invariance method is illustrated by the diagram below: Amplitude Parameters; Passband ripple = δ p Stopband ripple = δ p Discrimination Factor, We've been successful at creating taps vectors for low-pass and high-pass IIR filters in MATLAB and using those in IPP. In fact, if we call the ippsIIRGenLowpass_64f and ippsIIRGenHighpass_64f functions we get the same taps values as MATLAB so we're pretty confident with those.

On Wikipedia, it's defined as 2πfc/(2πfc+1) (where fc is the cutoff frequency). But here, a is defined as follows: 1 - e^-2πfc.
