Digital Circuit Fundamentals 1 Unit 2 – Asynchronous Ripple Counter
The maximum number of counts of a ripple counter may be controlled with feedback. This
action, or controlling of the count, is the modulus (sometimes abbreviated MOD) of the counter.
NEW TERMS AND WORDS
ripple counter - an asynchronous or serial counter in which the sections are triggered one at a
time, not simultaneously.
asynchronous - a related set of signals that do not change at the same period of time.
T, or toggle, flip-flop - a gate that alters its output state for each clock cycle.
modulus - the number of output states.
nibble - 4 bits of binary data.
word - 8 bits of binary data, or 2 nibbles.
