Active HIGH – if the state change occurs from a “LOW” to a “HIGH” on the clock’s pulse rising edge or during the clock width.The following list are terms commonly associated with a timing pulse or waveform. Sequential circuits can also change their switching state using either the rising edge, falling edge, or both edges of the clock signal as we have seen previously with the basic flip-flop circuits. Sequential logic circuits which use a clock signal for synchronization are dependent upon the frequency and therefore the clock pulse width to activate their switching action. In other words, the duty cycle for an astable timing pulse is 1:1. Astable multivibrators generally have an even 50% duty cycle, that is that 50% of the cycle time the output is “HIGH” and the remaining 50% of the cycle time the output is “OFF”.

Clock pulses are generally continuous square or rectangular shaped waveform which are produced by a single pulse generator circuit such as a Multivibrator.Ī multivibrator circuit oscillates between a “HIGH” state and a “LOW” state producing a continuous output. Simulation Files for SEQUENTIAL LOGIC from Learnabout-Electronicsĭownloading simulations for the first time? Check the instructions above.Individual Sequential Logic circuits can be used to build more complex circuits such as Multivibrators, Counters, Shift Registers, Latches and Memories.īut for these types of circuits to operate in a “sequential” way, they require the addition of some form of clock pulse or timing signal to cause them to change their state. To return to the main circuit, click Main in the File window at the left of the screen. Once the hand tool is selected, use it to click on any input to change its logic state, and observe the effects of different inputs on the circuit outputs.ĭouble clicking on a sub-circuit block reveals the hidden circuit within the block. To use the circuit simulation, make sure to click the simulation icon (the hand symbol − top left corner of the Logisim window).

Once you have downloaded Logisim, there are a number of ready made example logic circuits available to download from to accompany our Digital Electronics modules Note: Logisim works on most Desktop operating systems but current releases are not designed to work with Mobile platforms using iOS or Android, (See Logisim web site for details.) Using Logisim with Learnabout-Electronics

If you are not familiar with Logisim, (version 2.7.1) the program comes with its own Beginner’s Tutorial, User Guide and Library Reference that can be downloaded separately. Logisim is a free GNU program, and can be downloaded via the Logisim homepage. You can even modify any of the circuits, or use them as part of your own designs. To get you started, you can download a number of working logic circuits described in our Digital Electronics Module to see how the logic actually works.
