1 Now i want to swap the 2 differential inputs so that it can count down. The block diagram of 3-bit Asynchronous binary down counter is shown in the following figure. Asynchronous up down counter design.
Asynchronous Up Down Counter Design, If X 0 the device counts up. In other words this flip-flop produces complementing output. It is also used in Ring counter and Johnson counter.

0 1 2 3 0 1 2 3 etc. For a 4-bit counter the range of the count is 0000 to 1111. Mod 3 Mod 4 Mod 8 Mod 14 Mod 10 etc. This is mod 10 up counter with 7 segment displayYou can have down counter just by changing clock inputs of 234 flipflops from q to qbarYou can design both up and down counter in a single design with the help of mux.
The Mod 6 Down Counter While Output Is 5 Scientific Diagram.
2 I dont know how to shift this data serially. It counts from 2 ๐ 1 to 0. In other words this flip-flop produces complementing output. It is used more than separate up or down counter. Both up and down counters are designed using the asynchronous based on clock signal we dont use them widely because of their unreliability at high clock speeds. Since it is MOD-8 counter 3 T flip-flop are required.

Vhdl Code For Counters With Testbench Vhdl Code For Up Counter Vhdl Code For Down Counter Vhdl Code For Up Down Counter Coding Counter Counter Counter 2 I dont know how to shift this data serially. In an asynchronous counter all the clock inputs of the flip-flops have a unique input that is not shared with any other flip-flop in the system. It is used more than separate up or down counter. That is if 0 is given as the input 1 is produced at the output and vice versa.

4 Bit Asynchronous Up Down Counter Counter Electronics Circuit Logic HelloHere i explained how to design asynchronous updown counterThanks for watchingwatch my other videos alsoMy videosImportant days in June for the competi. While all gate circuits are limited in terms of maximum signal frequency the design of asynchronous counter circuits compounds this problem by making propagation delays additive. Exclusive-NOR XNOR Digital Logic Gate. Whereas for the up-down counter you can use multiplexers as switches as we saw in the design of the 3-bit synchronous up-down counter.

Full Adder Using Multiplexers Circuit Design Electronics Circuit Circuit As we know that in the up-counter each flip-flop is triggered by the normal output of the preceding flip-flop from output Q of first flip-flop to clock of next flip-flop. Synchronous counter has its flip-flops clocked at the same time whilst asynchronous counter is not. They are used in designing asynchronous decade counter. I have to design a counter with 2 differential inputsIt should count up in ive clock and count down during -ive clock cycleAlso it should shift the count serially.
