Six 4029 decade counters give the device a range of 1MHz. A set of 4511 BCD to 7-segment decoders translate the count to the display. A 4521 frequency divider chip uses an on-board 4.194304 MHz ...

Frequency dividers are usually realized on ICs and have a fixed and small division coefficient. In this article, a frequency divider is proposed that allows you to set the frequency division ...

The circuit here is an oscillator with an unusual frequency divider that I designed when I was ... The second IC (IC2) is a 74HC4017, a Johnson counter of which I used the Carry Out line (pin 12) as ...
