Hi,

I have an audio signal that should be routed into 4 different inputs (4 pots);
The 4052 analog switch seems to accomplish this: it's a DP4T.

It is controlled by a 2 bit sequence.

I want to use a momentary pushbutton switch, so that each time it's depressed, it sends a pulse.

My question:
How do I control the 2 bit sequence so that each time I press the pushbutton switch the count increases to next level? (= each time I press the signal goes to out 1, then 2, 3 etc.)

for ref. bit count is:
A0    A1    Dec
0      0      0
0      1      1
1      1      2
1      0      3

A binary counter, perhaps? any hints? links to some useful schematics?

Any help much appreciated.
