A flip-flop of the D type capable of loading data asynchronously and comprising two latches, a master and a slave one, connected in series with each other, is characterized in that each of these comprises an interface and selection circuit (MUX1,MUX2) for input signals transferable in ...
In the above image, a basicAsynchronous counter used as decade counterconfiguration using 4JK Flip-Flopsand oneNAND gate74LS10D. The Asynchronous counter count upwards on each clock pulse starting from 0000 (BCD = 0) to 1001 (BCD = 9). Each JK flip-flop output provides binary digit, and...

Let this time be T, then you could afford a system clock frequency as low as 1/T: you can probably use the pulse itself as clock input to set a flip-flop and then you use the system clock to sample and reset it. So the counter part would be kept synchronous and you can ...

(i.e. the write address value of the write counter910and the read address value of the read counter920) are equal. The last operation flip-flop950with the label “last” stores a Boolean value that indicates the type of the last operation. A write sets the value to 1, whereas a read...
If the BE line is low initially, and the AE line is high, a positive going RSA signal will cause flip-flop 26 to toggle such that the BE line goes high and the AE line goes low. Counter 20 is therefore reset to a zero address by the SEND SYNC signal which is passed by data sele...
PROBLEM TO BE SOLVED: To provide a flip-flop with asynchronous set/reset using the flip-flop with the asynchronous set and the flip-flop with the asynchronous reset. ;SOLUTION: This circuit is provided with the flip-flop circuit 3 with the asynchronous set, the flip-flop circuit 1 with the...
The Reset pulse will also preset the D-Type Flip-Flop 8 in this manner: the input pin of invertor 17 will go high causing its output pin to go low. This low output on the output pin of invertor 17 is connected to the preset input pin of the D-Type Flip-Flop 8 and will preset ...
