i'm not sure what you are looking for. a counter made of flip flops, ic's, gates? what have you so far?

Do you have a diagram there? any kind of IC's, gates that can count even numbers...

Pls help me.. diagram of a counter using flipflop or ic's that can count up to 31 and the output would be even numbers...

How about if you just build a 0 to 15 binary counter and then always force the least significant bit (Bit0) of the output to be a zero. Bit0 from the 4-bit counter will be Bit1 of the output, Bit1 of the 4-bit counter will be the Bit2 of the output, Bit2 of the 4-bit counter will be Bit3 of the output and Bit3 of the 4-bit counter will be Bit4 of the output.

hmm but i need 5bit binary counter... is a decoder needed for 5bit?

This is 5 bits. Bit0 of the output is always the value 0. This insures that the output is even. Then the four bits from the 4-bit counter make up bits 1 thru 4 of the output.

Do you have a diagram? because im a beginner with this counter.. i uses workbench..

It is really very straightforward. Build a textbook 4-bit counter the output of which would be as follows



Output of 4-bit counter would look like this:

BBBB DEC
3210
----
0000 0
0001 1
0010 2
0011 3
0100 4
...
1100 12
1101 13
1110 14
1111 15

The next step would be to append a constant "0" and
promote the four outputs from the 4-bit counter.

BBBB B DEC
4321 0
------
0000 0 0
0001 0 2
0010 0 4
0011 0 6
0100 0 8
......
1100 0 24
1101 0 26
1110 0 28
1111 0 30


Does that make it clearer?

Ok thanks.. I also need a diagram so that i can constract it in the workbench,, do you have a diagram for 5bit counter?

A lot of people come here expecting someone to do their homework don't expect a complete response.

This is available on the main website add more flip-flops, this is a down counter and uses a trick to use less parts so may not be what you need.

This has more complex examples.

I'd recommend getting a good book on digital electronics from your library, even an older one will do.
