What is the modulus of 5 bit ripple counter?

Explanation: The minimum number of flip-flops used in a counter is given by: 2(n-1)<=N<=2n. Thus, for modulus-5 counter: 22 <= N <= 23, where N = 5 and n = 3. Explanation: There are 10 states, out of which MSB is high only for (1000, 1001) 2 times.

What will be the frequency at the MSB output?

If your counter is modulo M, with M < 2^N (think of a decade counter such as 74LS90), then the frequency of the MSB will be f/M, but: The frequency of the MSB is no more f/(2^N), despite there are N flip flops.

What is the maximum count that can be contained in a ripple counter made of three JK flip flops?

23 = 8 values
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 23 = 8 values .

How many natural states will be there in a 5 bit ripple counter?

Each bit has propagation delay = 12ns. So, 5 bits = 12ns * 5 = 60ns.

What is the output frequency of the following circuit for 5 MHz clock signal?

Output Clock frequency = 20480000/4096 = 5000 i.e., 5 kHz. 13.

How do you find output frequency?

Answer : The output frequency of a waveform is defined as the CLOCK RATE DIVIDED BY THE NUMBER OF POINTS PER CYCLE. For example, if you create a waveform that has a record length of 1000 points and you create a 10-cycle sine wave, that waveform would have 100 points per cycle (1000 / 10).

What is limitation of ripple counter explain its solution?

Answer: The result is a binary count. They are called ripple counters because the new count ripples through them. The major disadvantage of ripple counters is that because of new count “rippling” through the flip flops all the bits of the count arrive at different times.

What is 3-bit ripple counter?

The number of states that a counter owns is known as its mod (modulo) number. Hence a 3-bit counter is a mod-8 counter. A mod-n counter may also be described as a divide-by-n counter.

What is 2 bit ripple up counter?

Binary Ripple Counter A Binary counter is a 2-Mod counter which counts up to 2-bit state values, i.e., 22 = 4 values. The flip flops having similar conditions for toggling like T and JK are used to construct the Ripple counter. Below is a circuit diagram of a binary ripple counter.

What is the ripple effect in counter circuits?

Counter circuits made from cascaded J-K flip-flops where each clock input receives its pulses from the output of the previous flip-flop invariably exhibit a ripple effect, where false output counts are generated between some steps of the count sequence. These types of counter circuits are called asynchronous…

How does the counter circuit work in a flip flop?

Since the counter circuit is positive-edge triggered (as determined by the first flip-flop clock input), all the counting action takes place on the low-to-high transition of the clock signal, meaning that the receiving circuit will become disabled just before any toggling occurs on the counter circuit’s four output bits.

How many bits can be produced from a j-k flip-flop?

Since we know that binary count sequences follow a pattern of octave (factor of 2) frequency division, and that J-K flip-flop multivibrators set up for the “toggle” mode are capable of performing this type of frequency division, we can envision a circuit made up of several J-K flip-flops, cascaded to produce four bits of output.

What are the Q outputs of each flip-flop for?

The Q outputs of each flip-flop will serve as the respective binary bits of the final, four-bit count:
