These sequences are achieved by forcing the counter to recycle before going through all of its normal states. A common modulus for counters with truncated sequences is ten. A counter with ten states in its sequence is called a decade counter. The circuit below is an implementation of a decade counter. Decade Counter. kessler flats broad ripple Jun 23, 2002 The simplest way is ripple cascading, which is appropriate for the 74LS90 family. We found that the 8 output in the modulo-10 counter is at 1/10 the frequency of the input.
