[mircemk] had previously built a frequency counter using an Arduino ... The project is relatively simple to construct, with an STM32F103C6 or C8 development board used as the brains of the ...
A good example comes via a project from [Scott, AJ4VD], a very simple frequency counter that uses a single 74 series chip at its business end, and counts to over 100MHz. The chip in question is a ...
Frequency tables can be used to help present sets of data. There are 4 children aged 10, which gives a total age of 40 in that category. There are 6 children aged 11, which gives a total age of 66 ...
