Which of the following IC can be used for frequency division by 5?
The 555 IC is one of the most frequently used integrated circuits. It is a simple Timer IC with a wide range of applications like pulse generation, Timing, oscillator etc. In this project, I will be using the 555 Timer IC as a Pulse Generator or Clock Generator for the Frequency Division operation.
How many flip flops are required to produce a divide by 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.
What is the output frequency of following circuit for 5 Mhz clock signal?
Output Clock frequency = 20480000/4096 = 5000 i.e., 5 kHz. 13.
What is divide by N counter?
A Divide by N counter implies that it divides the input clock frequency by N ie; if you cascade four flip-flops then, the output of every stage is divided by 2, if you are taking the output from the 4th flip-flop, then its output frequency is clock frequency by 16 (2^4).
Why a counter is called as divide by N frequency counter?
Both say that the counter can transition between ‘n’ states. It is called Divided by n because if you notice the frequency of MSB bit of a counter, it always has a frequency = freq(clk)/n. Hence the name.
Which flip-flop is used in counters?
Since there are only two states, a T-type flip-flop is ideal for use in frequency division and binary counter design. Binary ripple counters can be built using “Toggle” or “T-type flip-flops” by connecting the output of one to the clock input of the next.
How many flip-flops are needed to divide a signal 4?
2 flip-flops
To divide the frequency by 4 you need 2 flip-flops.

When a flip-flop is used to divide the clock frequency?
For frequency division, toggle mode flip-flops are used in a chain as a divide by two counter. One flip-flop will divide the clock, ƒIN by 2, two flip-flops will divide ƒIN by 4 (and so on).
How do you calculate flip-flops?
- The number of flip-flops required in a modulo N counter is [log2(N)].
- In electronics, a flip-flop is a circuit that has two stable states and can be used to store state information.
- The number of flip-flops required in a modulo N counter is.
- The modulus of a counter is given as: 2^n where n = number of flip-flops.
