Step 2: Choose the length M of the filter Filters are most useful (and best behaved) when M ≪ N. Step 3: Choose the form of the prior information Prior information ɛh = ɛHm (where h has K rows) and ɛ = σh/σd can improve the performance of the estimation process. Fo...

Thanks to the closed-form design of the filter, which guarantees sufficiently large stability margins even in the presence of uncertainty, our method ensures a satisfactory performance in a neighborhood of the operating point. The approach based on the inversion formulae results in a proper discrete...
This paper describes a new implementation of a DDFS using a second order IIR resonator, whose impulse response is a sine wave; as this impulse response can be expressed in a second order recursive form, sample generation only requires few multiplications and additions. Therefore, the idea is to...

(8.26)b(t)=sin(ωct)πt=sin(2πfct)πt The impulse response of a rectangular window filter has the general form of a “sinc” function: sin(x)/x. The filter coefficients, b[k], can be obtained from Equation 8.26 by taking discrete values, k, for the continuous time variable t....
