A Johnson counter is a type of digital circuit that can be used for a variety of applications. Here are some common applications of Johnson counters:
Frequency division: Johnson counters can be used to divide the frequency of an input signal. By cascading multiple stages of Johnson counters, the input frequency can be divided by powers of 2.
Shift register: Johnson counters can also be used as a shift register to store and shift binary data. By connecting the output of one stage to the input of the next, the Johnson counter can shift a binary number one bit at a time.
LED chaser: Johnson counters can be used to create an LED chaser circuit. By connecting the outputs of the Johnson counter to a set of LEDs, the LEDs will sequentially light up in a circular pattern.
Sequence generator: Johnson counters can be used to generate a sequence of binary numbers. By using the Q outputs of the Johnson counter, a sequence of binary numbers can be generated in a specific pattern.
Random number generator: Johnson counters can also be used as a simple random number generator. By using the Q outputs of the Johnson counter as the input to a XOR gate, the output of the XOR gate will produce a random sequence of binary numbers.
