In the door alarm example, the alarm goes off when all doors are shut, but using a sequential circuit, the alarm may stay on until a reset signal is applied. In this case, the purely combinational logic circuit may not be ideal. People want the alarm sound to remain until the ...
To be clear, a combinational loop is "bad". FPGAs are primarily intended for the implementation of synchronous digital logic. Synchronous logic has the characteristic that the design can thought of as a graph of interconnected combinatorial nodes (paths) which start at clocked startpoints and end...
depends not just on the current input, but also on the history of inputs. This contrasts with combinational circuits, where output only depends on the current input. A common example of a sequential circuit is a flip-flop or latch, which can hold and change its state based on its input....

Sequential logic is an important part of digital logic circuit, which is mainly composed of storage circuit and combinational logic circuit. Sequential logic is also called sequential logic circuit. It is different from other circuits that we are familiar with. Its output state at any time is det...
results. nor is the result of the negation of the or operator. it can also in principle be created from not and (nand) gates, which are considered universal gates. nor gates are widely used in both combinational and sequential logic circuits. how does a nor gate function in digital ...

Sequential logic makes use of cascaded bit latches to produce an asynchronous (async) digital counter. When a bit from the less-significant-bit (LSB) latch is made to clock the more significant bit (MSB), it is known as an async counter. In async, latches clock each other at slightly ...
