The students are required to design a special counter with an x input that counts the
digits/letters in your student ID as given below.
●
●
●
When x=1 counter must count forward, ie., if your student ID is 120202015, the counter counts
starting from the most significant digit 1 → 2 →0→20→
When x=0 counter must count backward, ie, 5 → 1-0→20→ starting from wherever the
last digit was during the previous count operation.
The counter must contain an asynchronous preset or clear input to force the counter to a known initial
state.
The counter output should be connected to a 7-segment display to demonstrate the correct operation.
a) Derive the state diagram, describe the meaning of each state clearly. Specify the type of the
sequential circuit (Mealy or Moore),
b) Determine the number of state variables to use and assign binary codes to the states in the state
diagram,
c) Choose the type of the FFs for the implementation. Give the complete state table of the counter,
using reverse characteristics tables of the corresponding FFs
d) Obtain Boolean functions for state inputs and output(s),
e) Draw the corresponding circuit diagram for the student ID counter,
