What is Johnson decade counter?
Johnson counter is used as a synchronous decade counter or divider circuit. It is used in hardware logic design to create complicated Finite states machine. ex: ASIC and FPGA design. The 3 stage Johnson counter is used as a 3 phase square wave generator which produces 1200 phase shift.
Which of the following is a decade counter?
Which of the following is a decade counter? Explanation: IC 7490 is called as decade counter or MOD-10.
What are the applications of counters and registers?
Counters are used as Digital clocks, Frequency counters, Binary counters etc. Serial in – serial out register are used for time delays. Serial in – parallel out registers are used for converting the data from serial form to parallel form. So these are also called “Serial to parallel converters”.
How is BCD counter implemented?
BCD counters follow a sequence of ten states and count using BCD numbers from 0000 to 1001 and then returns to 0000 and repeats. Such a counter must have at least four flip-flops to represent each decimal digit, since a decimal digit is represented by a binary code with at least four bits giving a MOD-10 count.
What is a decade counter IC used for?
A CMOS decade counter like 4017 IC includes a five-stage Johnson counter & 10 decoded outputs for counting up to 10 decimals. This IC can be used in different counter circuits such as an LED chaser light & also a non-contact circuit with an AC detector. This IC includes 16-pins where 10 & 16 pins are output pins.
How do you design a decade counter circuit?
BCD or decade counter circuit is designed by using JK flip flops and NAND gate. The BCD counter design is very simple, and it requires 4 JK flip flops because it is a 4-bit binary counter. The design of the decade counter is shown below. From the figure, we observe that the outputs of J and K are connected to logic 1.
What is BCD or decade counter circuit?

What is the truth table of decade counter?
The truth table of the decade counter is shown below. It counts the decimal input pulses and displays the output in binary form. The output of the NAND gate is zero when the input pulse count reaches 9 (1001). The inputs X1 and X3 of the NAND gate decode the count to display the output in binary form.
