Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types.
What states have 4 bit ring counters?
After that, at each clock pulse, the preseted 1 is shifted to the next flip-flop and thus forms a Ring. From the above table, we can say that there are 4 states in a 4-bit Ring Counter. In this way can design a 4-bit Ring Counter using four D flip-flops.
How many outputs does 4 inputs have?
So, a 4-input AND gate has 16 possible combinations, 5 inputs would be 32 outputs, and so on.
What is 4 bit ring counter?
4 bit Ring Counter. The ring counter is a cascaded connection of flip flops, in which the output of last flip flop is connected to input of first flip flop. In ring counter if the output of any stage is 1, then its reminder is 0. The Ring counters transfers the same output throughout the circuit.
Can or gates have 3 inputs? – Related Questions
How many types of ring counter are there?
There are two types of ring counters: A straight ring counter, also known as a one-hot counter, connects the output of the last shift register to the first shift register input and circulates a single one (or zero) bit around the ring.
What is an 8 bit ring counter?
8-bit ring counter can be realized by using 8 D latches, that are connected in series and by giving output of last latch as an input to the first latch. The output of first pulsed latch Q1 is connected as an input to second pulsed latch and so on. The clock pulses are generated using clock pulse generator circuit.
What is 4-bit ripple counter?
This circuit is a 4-bit binary ripple counter. All the JK flip-flops are configured to toggle their state on a downward transition of their clock input, and the output of each flip-flop is fed into the next flip-flop’s clock. So, when each bit changes from 1 to 0, it “carries the one” to the next higher bit.
How does a ring counter work?
A Ring counter is a synchronous counter. the synchronous counter has a common clock signal that triggers all the Flip-flops at the same time. Ring counter consists of D-flip flops connected in cascade setup with the output of last Flip-flop connected to the input of first Flip-flop. Each flip-flop constitutes a stage.
What is difference between ring counter and Johnson counter?
Recirculating a single 1 around a ring counter divides the input clock by a factor equal to the number of stages. Whereas, a Johnson counter divides by a factor equal to twice the number of stages. For example, a 4-stage ring counter divides by 4. A 4-stage Johnson counter divides by 8.
What is difference between ring counter and twisted ring counter?
It circulates a single ‘0’ or ‘1’ bit around the ring.
Difference between Straight and Twisted Ring Counter:
| STRAIGHT RING COUNTER |
TWISTED RING COUNTER |
| It is used in successive approximation and stepper motor control. |
It is used in phase shift or function generator. |
Which is faster ring or Johnson?
A ring is faster.
What is difference between latch and flip-flop?
The major difference between flip-flop and latch is that the flip-flop is an edge-triggered type of memory circuit while the latch is a level-triggered type. It means that the output of a latch changes whenever the input changes.
How many flip-flops are needed for Mod 16 ring?
A “mod-n” ring counter will require “n” number of flip-flops connected together to circulate a single data bit providing “n” different output states. For example, a mod-8 ring counter requires eight flip-flops and a mod-16 ring counter would require sixteen flip-flops.
How many flip flops are needed for a modulus 12 ring counter?
It is obvious that a mod-12 counter will require 4 flip-flops which when connected as a counter, will provide 16 states.
What is a mod 10 counter?
A decade counter is called as mod -10 or divide by 10 counter. It counts from 0 to 9 and again reset to 0. It counts in natural binary sequence.
