This Design Idea offers a practical approach to cascading two or more Johnson counters together with a bare minimum of parts. The CD4017 Johnson decade counter finds use in simple circuits ranging ...

I got some Geiger tubes a few days ago and built a very simple Geiger counter circuit that is powered entirely through the microphone jack (microphone connection provides a little power for things ...

Implementing standard UART communication required use of Silego’s GreenPAK analog and digital blocks, with the end result being a Geiger counter that offers real-time radiation measurement. The Geiger ...

Overview of digital logic design. Implementation technologies, timing in combinational and sequential circuits, EDA tools, basic arithmetic units, introduction to simulation and synthesis using ...

The challenge in measuring low frequencies is that the counter gate time is often too short for the signal relatively long period. This non-critical circuit automatically multiplies an input single ...
