Nov 5, 2015 · Design a circuit for an edge triggered 4-bit binary up counter (0000 to 1111). When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below figure) to design the circuit.

Design a synchronous up-down counter using J-K flip-flops that follows the below sequence. An input control signal x controls the direction of count sequence. Up: 1 → 3 → 5 → 7 when input x = 0, Down: 6 → 4 → 2 → 0 when input x = 1.

There are four states for any modulo–4 counter. The states are simple: 0, 1, 2, and 3. Let P be the number of flip–flops. Solve 2P-1 < N 2P. So 2P-1 < 4 2P and P = 2. We need two flip–flops. Step 3: Assign a unique P-bit binary number (state vector) to each state. Here P = 2, so we are assigning two–bit binary numbers.

Jan 21, 2021 · In this blog post we will design an electronic circuit using logics gates (combined into D-Type flip-flop circuits) to create a 4-bit binary counter. This approach will help us understand how a program counter may be designed within the CPU and automatically incremented for each tick of the clock cycle.

May 18, 2011 · I'm trying to design and test a 4-bit version of an Up/Down Counter using D Flip flops. I need it to be Up'/Down = 0 then the circuit should behave as an up counter. If Up'/Down = 1 then the circuit should behave as a down counter.

May 30, 2024 · In its 4-bit form, the counter incorporates four such flip-flops, representing binary values from 0000 up to 1111, corresponding to the decimal range of 0 to 15. This counter's distinct feature is its bidirectional counting capability, governed by external inputs commonly marked as 'UP' and 'DOWN.'

A bidirectional counter is a synchronous up/down binary counter that has the ability to count in both directions either to or from some preset value as well as zero.

Dec 3, 2017 · Get the basic truth table (or equations or whatever) that achieves the goal of the problem as cleanly as possible. Everything else is implementation details. I don't like to mix them if I can avoid it so that my mind can focus on them one at a time.

Nov 10, 2012 · could anyone please help me by finding the truth table, State Diagram, and Timing Diagram for the pictured circuit in the attachment section?

Aug 21, 2018 · Slight changes in AND section, and using the inverted output from J-K flip-flop, we can create Synchronous Down Counter. A 4-bit Synchronous down counter start to count from 15 (1111 in binary) and decrement or count downwards to 0 or 0000 and after that it will start a new counting cycle by getting reset.
