Synchronous overlapping sequence detector that detects the bit patterns 010 and 1001 using J-K flip flops.

Synchronous overlapping sequence detector that detects the bit pattern 101 using J-K' flip flops (74LS109).

if x,y = 0,0

next state is same state

if x = 0,y = 1

next state is plus 1

if x = 1 ,y = 0

next state is minus 1

if x,y = 1,1

next state reset to 0

A 5-bit pseudo random number generator. Uses 5 D Flip-Flops to form a linear feedback shift register. The generator stops when put in a lock state of 00000. Push the button to start.

This is a simple digital clock with basic combinational and sequential logic circuits.

It can display seconds, minutes, and hours

Users can set time by clicking the button and using the multiplexer to choose which to change.

Also, the design for the 4bits 7segment display and 3 bits 7segment display is inside.

ASYNCHRONOUS SEQUENTIAL CIRCUIT

Sequentially display the digits 5-8-6-5

This is an 8-bit sequential multiplier with an 8-bit output. It works by adding A to itself B number of times using an accumulator to keep track of what the value should be. Once the number of times A was added to itself is equal to B then it signals to the output and updates the data. 

The output of the circuit is high when '110' is detected. Overlapping is allowed. The circuit is built using a Mealy statemachine.
