摘要: The authors study the stability of sigma-delta modulators with second-order FIR (finite impulse response) noise transfer functions. At present, there is no analytical criterion which both necessary and sufficient for such systems, even when input known. present a variety tests, culminating results simple computer algorithm proves zero-input 94% foregoing type are, according to brute-force simulations, believed be stable. may extended higher-order FIR, or IIR (infinite functions also modified incorporate bounded inputs. >
