    Hello,

    Take a look at this page : http://it029000.massey.ac.nz/notes/59233/lect6.html
    It comes from this page of the EDUCYPEDIA :
    http://www.educypedia.be/electronics/digitacounters.htm

    There are more pages on digital electronics over there too.

    Digital electronics:
    Arithmetic circuits D/A-A/D converters Number systems Codes and decoders Flip flops Technology Counters and registers General overview Technology-CMOS Digital logic Memories Technology-TTL Timers and oscillators

    Greetings,

    Hello,

    On the first page I gave you was a 4 bit shiftregister shown.

    If you get rid of the last one of the D-flipflops, you will end up with a 3 bit as you want it.
