For example, a binary coded decimal counter is used to count from. 0 to 9 (10 different states) is a mod-10 counter. A counter with N flip-flops has a maximum of 2N states (maximum modulus is 2N). The counters are typically built up from JK, T or D flip-flops.

Counters are sequential logic circuits that counts the pulses applied at their clock input. They usually have 4 bits, delivering at the outputs the corresponding binary code of the number of pulses occurred at the input. The counters can be classified according to: - the counting mode: - up counters – count up from Synchronous integrated meter : 4520, Meter-dividers by N, Meter integrated modulo 10 : 7490 The Q2 exit of the second rocker of the meter modulo 4 must provide as for it, the most significant bit (MSB), it is what is represented on the figure 22.

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. Its duty cycle is not 50% (this can be arranged if necessary by biquinary counting, discussed below), but this is of no consequence. broad ripple parking garage (Shift registers, Ripple counter, Synchronous binary counters, other counters).
