How can JK flip flop be used as a counter?
A binary counter can be constructed from J-K flip-flops by taking the output of one cell to the clock input of the next. The J and K inputs of each flip-flop are set to 1 to produce a toggle at each cycle of the clock input.
How many flip-flops are required to construct a decade counter 10 states?
four flip-flops
Then a decade counter has four flip-flops and 16 potential states, of which only 10 are used and if we connected a series of counters together we could count to 100 or 1,000 or to whatever final count number we choose. The total number of counts that a counter can count too is called its MODULUS.

How many flip flops are needed for a mod 20 counter?
because it is 2^ n,where n are number of flip-flops. so for MOD-20 COUNTER 5 flip-flops are required.
Where are JK flip flops used?
JK Flip Flop is a universal flip-flop that makes the circuit toggle between two states and is widely used in shift registers, counters, PWM and computer applications.
What is J-K flip-flop truth table?
Truth Table: When both of the inputs of JK flip flop are set to 1 and clock input is also pulse “High” then from the SET state to a RESET state, the circuit will be toggled. The JK flip flop work as a T-type toggle flip flop when both of its inputs are set to 1. The JK flip flop is an improved clocked SR flip flop.
How many flip flops are required to produce a 64 device?
As straight forward ripple counter divides the clock by 2 at each flip flop and since 2 x 2 x 2 x 2 x 2 x 2 = 64 it can be done with six flip flops.
How many flip-flops are needed for Mod 31?
15 flip-flops
48. the number of flip-flops required to build a mod-31 counter is (a) 15 flip-flops.
