Design a stepper motor controller for half step mode in
MultiSim.
The following will be your inputs:
CLOCK – A 1Hz clock signal
RESET – A SPST switch configured as an input to reset the
system
DIRECTION – A SPST switch that determine the direction. HIGH for
clockwise and LOW for counterclockwise
Be sure to include each of the following:

State Assignments
Next State Table
Boolean equations for next state logic and output logic

Design and analyse of a circuit which turns a DC motor at a
speed which is proportional to how much a temperature is away from
a set temperature, and turns:
Clockwise when temperature is greater than (say) 25 degrees
C.
Anticlockwise when the temperature is less than (say) 20 degrees
C.
Such a circuit might be used to regulate the temperature of a
room by turning a ceiling fan to move warm air in/out of that room

Design a linear-time algorithm which, given an undirected graph
G and a particular edge e in it, determines whether G has a cycle
containing e. Your algorithm should also return the length (number
of edges) of the shortest cycle containing e, if one exists. Just
give the algorithm, no proofs are necessary. Hint: you can use BFS
to solve this.

Design an experiment in which you would perform some sort of

replicates will you collect? What will be the form of the data you
collect and what test will you perform? What is your null and
alternative hypothesis?
