Logic Diagram Of Mod 5 Counter. So in general an n bit ripple counter is called as modulo n counter. Timing diagram of asynchronous decade counter and its truth table in the above image a basic asynchronous counter used as decade counter configuration using 4 jk flip flops and one nand gate 74ls10d.
Most common type of counter is sequential digital. 2 n n 2 n 5 n 3 ie. This will be given to the reset inputs of the counter so that as soon as count 110 reaches the counter will reset.
A counter is a device which can count any particular event on the basis of how many times the particular event s is occurred.
Steps to design synchronous 3 bit updown counter. Logic diagrams v objectives terminal objective 10 given a logic diagram read and interpret the diagrams. Thus reset logic is or of complemented forms of qc and qb. It is obvious that a mod 12 counter will require 4 flip flops which when connected as a counter will provide 16 states.
