NAME

biquad − Biquad IIR filter
|
SYNOPSIS
DESCRIPTION
|
Biquad IIR filter. Implements the following transfer
function: H(z) = (n0 + n1z-1 + n2z-2) / (1+ d1z-1 +
d2z-2)
|
FUNCTIONS
|
biquad.N (uses floating-point) |
PINS
|
biquad.N.enable bit in (default:
0) |
|
Filter enable. When false, the in is passed to out
without any filtering. A transition from false to true
causes filter coefficients to be calculated according to
parameters
|
|
biquad.N.valid bit out (default:
0) |
|
When false, indicates an error occured when caclulating
filter coefficients.
|
PARAMETERS
|
biquad.N.type u32 rw (default:
0) |
|
Filter type determines the type of filter coefficients
calculated. When 0, coefficients must be loaded directly.
When 1, a low pass filter is created. When 2, a notch filter
is created.
|
|
biquad.N.f0 float rw (default:
250.0) |
|
The corner frequency of the filter.
|
|
biquad.N.Q float rw (default:
0.7071) |
|
biquad.N.d1 float rw (default:
0.0) |
|
1st-delayed denominator coef
|
|
biquad.N.d2 float rw (default:
0.0) |
|
2nd-delayed denominator coef
|
|
biquad.N.n0 float rw (default:
1.0) |
|
non-delayed numerator coef
|
|
biquad.N.n1 float rw (default:
0.0) |
|
1st-delayed numerator coef
|
|
biquad.N.n2 float rw (default:
0.0) |
|
2nd-delayed numerator coef
|
|
biquad.N.s1 float rw (default:
0.0) |
|
biquad.N.s2 float rw (default:
0.0) |
