registers

Hi! I'm not really much familiar with Logisim simulations. We were asked to do a T implementation of a Shift left and shift right register. I know how to do the 4 bit shift left and shift right register (there are samples already online) but not the "T implementation" part. Do you have any idea...

I need to design an Automated system such that a user gives inputs in 3 bits and there's a clock running that resets itself and gives a positive signal after the time indicated by input. We can use logic gates, combinatorial circuits, sequential circuits, counters, registers.
