What is a frequency divider circuit?

A Frequency Divider is a circuit that divides a given frequency by a factor of n, where n is an integer. For example, if the frequency of the Input signal to a Frequency Divider is FIN, then the frequency of the output generated by the Frequency Divider Circuit is given by. FOUT = FIN / n, where n is an integer.

How many flip flops are required to produce a divide by 128 device?

How is IC 555 timer used as frequency divider?

The 555 timer can be used in monostable mode to divide a known frequency. This is due to the fact that the 555 cannot be retriggered during its timing cycle. The simple frequency divider circuit is actually the basic circuit of a 555 in monostable (one shot) mode.

How to wire IC 4013 as a frequency divider?

To wire IC 4013 as a Frequency divider all we have to do is wire the complement pin Q’ to the data input D of the flip flops. The feedback signal of the complement Q pin to the data input divides the clock signal frequency by half.

What voltage can the 4013 take?

The 4013 can actually take a wide range of voltage, anywhere from 3V-15V. The 4013 is composed of 2 independent flip flops, labeled on the input as flip flop 1 and flip flop 2. Each flip flop has 6 pins attached to it. The clock pin is the pin where we feed a clock signal. The 4013 executes instructions on the rising edge of a clock signal.

How do we connect a clock signal to the 4013?

We connect a clock signal to the clock of the 4013, which is pin 3. This clock pin can be obtained from a number of sources such as a frequency generator. Or a 555 timer chip. Or a 4046 chip.

What is frequency divider circuit?

This Frequency divider circuit was built around Timer IC1 555 which feeds the source pulse and IC2 4013 a dual D type flip flop which divides the incoming pulse frequency. IC 555 was wired as an astable multivibrator and this forms the source of the clock pulse.
