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)
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
