AI Thread Summary
A latch is not a type of flip-flop; rather, it stores data based on the level of a clock signal, while a flip-flop captures data on the edges of the clock signal. Flip-flops can be constructed from gated latches, which are themselves derived from basic latches. The discussion suggests experimenting with a 74LS series gated latch chip to create a flip-flop. Additionally, a gated SR latch can be utilized to form an SR flip-flop by incorporating a custom pulse transition detector to convert level changes into short spikes. Understanding these relationships clarifies the hierarchy of latches and flip-flops in digital circuits.

Is latch a type of flip-flop? I'm confuse.
 
Engineering news on Phys.org
basically a latch stores data on one of the levels of a clock signal (when the signal is either 1 or 0), while the flip-flop stores data on one of the edges of the clock signal (either falling edge or rising edge).

FF is a type of Latch

Using a Latch, you can make a Gated Latch.

Using a Gated Latch, you can make a Flip Flop.

So, FFs are a subset of Gated Latches, which are subsets of the basic Latch (two transistors).


Have you tried using a 74LS series Gated latch chip (don't remember exact part number) to make a Flip Flop? Try it!

Use a gated SR Latch to make an SR Flip Flop.. how? Before the Gate input... make your own custome Pulse Transition Detector.

So your PTD circuitry has to convert a level change into a short spike. You figure a circuit out! (There are a bilion ways to do this)
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
