What is the modulus of 6 bit ripple counter?

In the modulus-6 counter, there is a total of six states (0 to 5). From the above diagram, it is clear that the minimum number of flip-flops (n) required to design a mod-6 counter is, M<2n 4<2n or n=3.

How do you draw a ripple counter?

Design Problem #1

  1. Step 1: Find the number of flip-flops. BCD is the 4-bit number and there are 9 valid states in a 4-bit BCD.
  2. Step 2: Choose the type of flip-flop.
  3. Step 3: Draw the truth table for BCD ripple counter.
  4. Step 4: Use Kmap to find the reset logic function.
  5. Step 5: Draw the logic circuit diagram.

What is mod in ripple counter?

The 3-bit ripple counter used in the circuit above has eight different states, each one of which represents a count value. Similarly, a counter having n flip-flops can have a maximum of 2 to the power n states. The number of states that a counter owns is known as its mod (modulo) number.

How do you design a mod 6 counter with IC 7490?

How do I Make a Mod 6 Counter by Using a 7490 IC Chip?

  1. Insert the 7490 into the breadboard.
  2. Locate the 7490 pins labeled “VCC” and “GND.” Refer to the 7490 datasheet for the pin description.
  3. Locate the 7490 pins labeled “R9(1)” and “R9(2).” Use jumpers to connect both pins to breadboard ground.

What is a mod 6?

The “mod 6” means that we are working only with the remainders of numbers after division by 6, and not really working with the integers at all. Note that this word “mod” is different from the modulus operator used in programming languages. Even though “4+3 = 1 mod 6” in English is true, “4+3 == 1%6” in C is false.

How many values can a ripple counter count up to?

In the 3-bit ripple counter, three flip-flops are used in the circuit. As here ‘n’ value is three, the counter can count up to 2 3 = 8 values .i.e. 000,001,010,011,100,101,110,111. The circuit diagram and timing diagram are given below.

How does a ripple counter work?

An n-MOD ripple counter contains n number of flip-flops and the circuit can count up to 2 n values before it resets itself to the initial value. These counters can count in different ways based on their circuitry. UP COUNTER: Counts the values in ascending order. DOWN COUNTER: Counts the values in descending order.

How do you make a modulo 6 counter?

A modulo 6 (MOD-6) counter circuit, known as divide-by-6 counter, can be made using three D-type flip-flops. The circuit design is such that the counter counts from 0 to 5, and then on the 6th count it automatically resets to begin the count again. Since we are using the sixth count itself to cause a reset, it is unstable.

How many flip flops do I need for a mod 6 counter?

Recall that the number of flip-flops required for a Johnson counter is half the number of used states for that counter. Since a mod 6 Johnson counter can count up to 6 states, 3 flip flops will be required.
