<p>A two-stage filter for a circuit protection device. The filter includes a first filtering device connected to receive an input signal v, the first filtering device generating an intermediate signal v1, whereinwhere k is a sample index and h0 . . . h20 are first filter coefficients. A second filtering device filters the intermediate signal to generate an output signal v2, whereinwhere g0 . . . g74 are second filter coefficients. A Fourier algorithm is applied to the output signal to generate a control signal for the circuit protection device.</p> |
