A continuous-time signal can be represented by a discrete-time signal consisting of a
sequence of samples x (n)= x_ a (nT). It is often necessary to change the sampling rate of a …

This paper introduces a practical and straightforward view on the design of circuit based on
electronically controllable current conveyors (ECCIIs), wide-band operational …

This paper proposes a novel monostable multivibrator featuring compact topology and
current-tunable property. The proposed circuit was composed of a single differential input …
