On logisim or any circuit building program, design a counter that counts 9,8,7,6,5,4,3,2,1,0 then back to 9. After, add to it's output a 7 segment decoder and it's display.

thank you!

We will be using D-Flip Flop for the Implementation as D - Input is same as next state expressions derived below using K-Maps.

Question 3: A)Design a BCD counter. -The circuit counts from 0 to 9, then resets back to 0 to restart the counting sequence. -The circuit has one input run/stop. If the input is 1, the eounter will count. If the input is 0, the counter will freeze in its current location until the input is set to 1 again. -The circuit has one output. It becomes 1 when the counter completes a cycle and starts the next one. Otherwise, that...

Design a circuit using PIC 18F458, which counts the number of input pluses read by any input I/O port of the PIC 18 and show the pulses counting state on the 7-segment display. Hint: For Input pulses function generator or 555 Astable oscillator can be used.

(a) Design an FSM (only state diagram and state table) for a 3-bit counter that counts through odd numbers downwards. Assume the reset state to be the lowest value of the counter. Use an active low reset to reset the counter. (b) Write a behavioral VHDL code that implements the FSM. (c) Write a VHDL test bench to test the FSM.

Objective: Design, construct, and test a three-bit counter that counts up or down. An enable input E determines whether the counter is on or off.  If E=0, the counter is disabled and remains at its present count even though clock pulses are applied to the flip-flops.  If E=1, the counter is enabled and a second input, x, determines the direction of the count.  If x=1, the circuit counts upward with the sequence 000, 001, 010, 011, 100,...

Design the circuit that gives the total number of your school number as an asynchronous counter. If 4 + 6 + 0 + 4 + 1 + 8 + 0 + 4 + 0 = 27, Mode 28 counter will be designed. FF with negative edge triggering will be used. You will definitely show the clock pulse, input and output connections of the FFs you will use. Otherwise, you will not get points because the counter will not work or...
