Introduction: Digital Clock Using Crystal Oscillator & Flip Flops Clocks are found in almost all types of electronics, they are the heartbeat of any computer. They are used to synchronize all sequential circuitry. they are also used as counters to keep track of time and date. In this instruct...
The frequency at the output Q compared to the input clock CLK frequency is divided by two. Using 2 flip flops, a divide-by-4 ripple counter is obtained. By cascading n flip flops, we get a divide by 2n counter.Ring Counter - A ring counter is a Shift Register (a cascade connection ...

A simple binary weighted counter can be made using T flip-flops. The flip-flops are attached to each other in a way so that the output of one acts as the clock for the next, and so on. In this case, the position of the flip-flop in the chain determines its weight; i.e., for...
Timing diagrams illustrate, or at least attempt to illustrate, what occurs when various digital signals are in their respective states. It’s called a “timing” diagram because usually you’re using a clock signal as a reference, but we haven’t looked at clock lines yet (soon!). ...
Depending on SET, either the 1 PPS (Pulse Per Second) or the 1 PPH (Pulse Per Hour) clock drives the Hour circuit. The 12H clock counts from 00 to 11 rather than 01 to 12. Hint - use regular JK flip flops (74LS73) instead of the 74LS93 so on terminal count, the counter ...
In this tutorial, we will learn about the procedure of conversion flip-flops, and how one type of flip-flop can be converted into another type of flip flops in Digital Electronics.
Dividing Clocks with the Simple Flip Flop Method Most sites recommend using normal flip-flops to divide a clock. You can Google around for more detail, but in our schematic we use aD-Flip-Flopto toggle back and forth between a 1 and a 0 by feeding back the opposite of the data to the...
This entryshows the whole thing working, with a similar circuit to the one posted above. So, yes, it worked! So, let us know if you're able to create your own clock multiplier using this information. Good luck, and have fun!
Flip-flops A device that stores either a 0 or 1. Stored value can be changed only at certain times determined by a clock input. New value depend on the current state and it’s control inputs. A digital circuit that contains filp-flops is called a synchronous sequential circuit. ...
