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 ...

[David Johnson-Davies] recently built a proof ... It’s a simple implementation, a set of frequency dividers that blink three LEDs with up to a 90 MHz input signal. But the simplicity is the ...

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 first measures the period with a 100-Hz time-base frequency, which holds the binary reading in a 74HC4040 counter, and then loops are made to determine how many times that period fits ...

Central to this expansion are the active frequency dividers that boast an impressive input frequency range of 6.5 GHz to 16.5 GHz. Their output spectrum stretches from 13 GHz to an astounding 33 ...

The 5-bit programmable CMOS low-frequency divider consists of an asynchronous pulse counter, a control logic and a multiplexer that is able to commuta ...
