hello,
can anyone help me how to get a 1 hertz timebase for a ttl digital clock? i already tried to use the 60Hz frequency from a 220VAC outlet and divide it down to 1Hz using a mod60 counter but still not getting that exact 1Hz freq. output...i dont get it...i am really having a hard time on this one.
And can you pls include a schematic, i would greatly appreciate any help from you guys.
