Memory in logic gates for specified time intervals

AI Thread Summary
To hold an output in memory for a specified time despite changing inputs, a flip-flop or latch can be utilized, which is a memory storing element created using NOR or NAND gates. For digital inputs, these components effectively retain the output until a new input is received after the designated time interval. In cases where the input is an analog signal, a "sample and hold" circuit is recommended to achieve similar functionality. Understanding these components is crucial for designing circuits that require temporary memory storage. Utilizing flip-flops or sample and hold circuits will meet the design requirements effectively.

I am a physics student new to the world of electronics and I have a question that may turn out to be very simple. What I am trying to design requires that a single output given some input be held in memory for a specified time despite any differing input being sent through during that time interval. Then after the time interval the output is immediately dependent on any new input. Any suggestions would be useful.

refer to flip -flop .
it is a memory storing element formed by NOR or NAND gate .
 
If the input is digital that the thing you are referring to is called a latch (or flipflop).

If the input is an analog signal then the thing you're referring to is called a "sample and hold".

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
