6.3.6. Setting Up Second Order IIR Filter

  1. Enter values for the IIR filter.
    Table 5.  IIR Filter Parameters
    Parameter Values Description
    Fn (Hz) 2 to 8000 The ‘natural frequency’ of the filter numerator, Ωn/2π.
    Fd (Hz) 2 to 8000 The ‘natural frequency’ of the filter denominator, Ωd/2π.
    Zn (nondimensional) 0 to 1000 The damping factor of the filter numerator, ζn. Values less than 0.707 produce a trough around Fn before the numerator gain increases; larger values give a smoother (more damped) characteristic.
    Zd (nondimensional) 0 to 1000 The damping factor of the filter denominator, ζd. Values less than 0.707 produce a peak around Fd before the denominator gain decreases; larger values give a smoother (more damped) characteristic.
    On/Off On or off. Switches the filter on or off.
    Input gain 0 to 1 This gain is in series with the filter and multiplies the complete control loop. Default to 1, but set to smaller values to reduce the overall control loop gain if required to improve control loop stability.
