What is 4-bit synchronous up counter?
What is 4-bit synchronous up counter?
4- Bit Synchronous Up Counter An external CLK signal is given to all four flip-flops in parallel. This counter includes 16 output states where it counts from 0000 to 1111. As compared to 3-bit, the timing diagram of this counter & its operation is also the same.
How many effects are required for 4-bit up down counter?
Explanation: An n-bit bit counter requires n number of FFs. In a 4-bit up-down counter, there are 4 J-K flip-flops required. For modulus-10 counter, N = 10. Therefore, 23 < = 10 < = 24.
What is 4-bit down counter?
It is a group of flip-flops with a clock signal applied. Counters are broadly divided into two categories – Asynchronous or ripple counters. Synchronous counters.
How many natural states will there be in a 4-bit ripple counter?
1. How many natural states will there be in a 4-bit ripple counter? Explanation: In an n-bit counter, the total number of states = 2n. Therefore, in a 4-bit counter, the total number of states = 24 = 16 states.
What is a 4-bit down counter?
What is a 4 Bit synchronous counter waveform?
4-bit Synchronous Counter Waveform Timing Diagram Because this 4-bit synchronous counter counts sequentially on every clock pulse the resulting outputs count upwards from 0 (0000) to 15 (1111). Therefore, this type of counter is also known as a 4-bit Synchronous Up Counter.
How does a 3bit synchronous up and down counter work?
3bit synchronous up/down counter or Bidirectional counter Depending on the control input, the counter will count either upward or downward. If the counter counts in an upward direction, it will count from 0 to 7. When the control input is changed, the counter will count in a downward direction from 7 to 0.
How does the 4-bit counter work?
Normally the counter increments the 4 bit word (Q4,Q3,Q2,Q1) by one every time the clock input is toggled. If the UP/DOWN input is asserted the counter counts down (subtracts one) upon each clock cycle instead.
What are the output states of a 3-bit counter?
Since it is a 3-bit counter, it has 8 possible output states. Depending on the control input, the counter will count either upward or downward. If the counter counts in an upward direction, it will count from 0 to 7. When the control input is changed, the counter will count in a downward direction from 7 to 0.
