Abstract This paper contains implementation of 2-bit ripple upcounter with 555 timer Astable multivibrator as clock circuit. The most widely used application of ripple up counter is to act as an ...

The classic and versatile 555 finds its way into many low to moderate frequency oscillator applications. Some of these require the ability to selectively gate oscillation on and off on demand and the ...

A transistor logic memory module based on the Royer oscillator type magnetic multivibrator is described, in which six coils tightly wound around a HTcSC thin disk core are connected to two switching ...
