This paper proposes a high-input impedance voltage-mode (VM) multifunction biquad filter which employs three current-feedback amplifiers (CFAs), resistors, and two grounded capacitors. The proposed VM has single-input triple-output can realize non-inverting low-pass (NLP), inverting band-pass (IBP), band-stop (NBS) voltage responses at the same time without increasing component selection. enjoy...

The specifications analysis for an MVB (Multifunction Vehicle Bus) bus administrator showed that system-on-a-chip strategies should be adopted to cope with its great complexity. Particularly, a new hardware/software codesign methodology has been followed. Its main concept is that the MVB devices (the bus administrator itself and the less complex devices) constitute a “progressive family”. This ...

Myoelectric systems have received widespread use as controls of prosthetic devices for individuals with amputations or congenitally deficient upper limbs, (Parker and Scott, 1988). Many systems are now available commercially to control a single device (hand, elbow, wrist). These systems extract a control signal based on an estimate of the amplitude, (Dorcas and Scott, 1966), or on the rate of c...
