Abstract :
Through the intermediary of state-variable equations, an equivalence is obtained which shows how passive RC circuits incorporating time-variable gyrators can be used to realise N-path filters. The effects of gyrator losses in the realisation of time-invariant transfer functions are briefly discussed to indicate the practical significance of the result.
